Ventricular Hypertrophy: From 1 Different Sources

Enlargement of the ventricular chambers of the HEART, a common complication of HYPERTENSION and coronary artery disease (see HEART, DISEASES OF). Treatment is of the underlying conditions and cardiac drugs which facilitate the working of the heart.

Ventricular Fibrillation

A very fast ‘flickering’ of the heart with no measurable circulation of blood by the heart. This usually occurs after a heart attack (or electrocution).... ventricular fibrillation

Ventricular Septal Defect

An inherited defect of the HEART. The septum (partition) separating the two ventricles is pierced by a hole which, if large, results in blood being diverted to the LUNGS at a greater pressure than normal. This may lead to irreversible PULMONARY HYPERTENSION, which early surgical intervention (repair of the septal defect) should prevent. A quarter of patients with VSD have other cardiac defects. Half of the defects seal themselves spontaneously.... ventricular septal defect

Hypertrophy

The increase in size which takes place in an organ as the result of an increased amount of work demanded of it by the bodily economy. For example, when valvular disease of the heart is present, compensation occurs by an increase in thickness of the heart muscle, and the organ, by beating more powerfully, is able to overtake the strain thrown upon it. Similarly, if one kidney is removed, the other hypertrophies or grows larger to take over the double workload.... hypertrophy

Ventricular Tachycardia

A serious cardiac arrhythmia in which each heartbeat is initiated from electrical activity in the ventricles rather than from the sinoatrial node in the right atrium.

It is caused by an abnormally fast heart-rate due to serious heart disease, such as myocardial infarction or cardiomyopathy.

It may last for a few seconds or for several days.

Diagnosis is confirmed by ECG.

Emergency treatment is with defibrillation and an antiarrhythmic drug.... ventricular tachycardia

Benign Prostatic Hypertrophy, Or Hyperplasia

(BPH) The benign buildup in the prostate of “warts” or epithelial neoplasias that can block or interrupt urination, and which are usually concurrent with moderate prostate enlargement. They cause a dull ache on urination, ejaculation, and/or defecation. The diagnosis is medical, since the same subjective conditions can result from cancer of the prostate. BPH is common in men over fifty and can be the result either of diminished production of complete testosterone or poor pelvic circulation. Alcohol, coffee, speed, and antihistamines can all aggravate the problem.... benign prostatic hypertrophy, or hyperplasia

Heart – Left Ventricular Failure (lvf)

Failure of the left ventricle to receive blood from the pulmonary circulation and to maintain efficient output of incoming blood to the arterial system. Failure to do so leads to congestion of blood in the lungs followed by fluid retention. If uncorrected, leads to kidney disturbance, low blood pressure, cyanosis (blueness of the skin). Onset may be tragically sudden.

Failure of the left ventricle may occur in cases of pericarditis, disease of the aortic valve, nephritis or high blood pressure.

Left ventricular failure is often of sudden onset, urgent, and may manifest as “cardiac asthma”.

Causes: blood clot, anaemia, thyroid disorder, coronary disease, congenital effects, drug therapy (beta blockers, etc), and to fevers that make heavy demands on the left ventricle.

Symptoms: breathlessness, wheezing, sweating, unproductive cough, faintness, bleeding from the lungs, palpitation. Cardiac asthma at night: feels he needs air; better upright than lying flat. Exertion soon tires. Sensation as if heart would stop. Blueness of lips and ears from hold-up in circulation of the blood through the lungs. Frequent chest colds. Awakes gasping for breath. Always tired. Cold hands and feet. Symptoms abate as compensation takes place. ‘Cream and roses’ complexion. The failure of left ventricle soon drags into failure of the right ventricle.

Right ventricular failure leads to congestive heart failure, with raised venous pressure in neck veins and body generally, causing oedema, ascites and liver engorgement.

Treatment. Agents to strengthen, support, and eliminate excess fluids from the body. BHP (1983) advises four main remedies: Hawthorn, Motherwort, Broom and Lily of the Valley. The latter works in a digitaloid manner, strengthening the heart, contracting the vessels, and lessening congestion in the lungs. Tinctures. Hawthorn 2; Stone root 1. Lily of the Valley 1. Dose: 15-45 drops thrice daily.

Broom tea. 2 teaspoons flowers, or 2-3 teaspoons tops and flowers, in cup water brought to boil and simmered one minute. 1 cup freely.

To remove fluid retention in the lungs, diuretics are indicated; chief among which is Dandelion root because of its high potassium content to prevent hypokalaemia. Dandelion coffee. As urinary excretion increases, patient improves.

Vitamin E. Not to be taken in left ventricular disorders.

Diet. See entry: DIET – HEART AND CIRCULATION.

UK Research. Researchers found that left ventricular failure was reduced by a quarter when patients were given magnesium intravenously for the first 24 hours after admission to the coronary care unit. They conclude that it should be given before any other heart therapy is commenced, and that patients should receive regular infusions if no other drug treatment is used. (The Lancet, 2.4.1994). This supports the use of magnesium sulphate (Epsom’s salts) by a past generation of herbal practitioners for the condition. ... heart – left ventricular failure (lvf)

Ventricular Ectopic Beat

A type of cardiac arrhythmia in which abnormal heartbeats are initiated from electrical impulses in the ventricles of the heart. In a normal heart, beats are initiated by the sinoatrial node in the right atrium.

Ventricular ectopic beats may be detected on an ECG.

If there are frequent abnormal beats that cause symptoms, or beats that arise from more than 1 site in the ventricles, treatment with an antiarrhythmic drug may be required.... ventricular ectopic beat

Asymmetric Septal Hypertrophy

(ASH) see hypertrophic cardiomyopathy.... asymmetric septal hypertrophy

Ventricular Assist Device

(VAD) a mechanical pump implanted in the body for the purpose of taking over some or all of the pumping action of the heart in patients with severe heart damage. Support may be given to the left ventricle (LVAD), right ventricle (RVAD), or both. Most such devices require *thoracotomy, but a percutaneous device is now also available. This is usually regarded as a temporary measure until the heart has recovered or is transplanted.... ventricular assist device

Heart – Right Ventricular Failure (rvf)

Failure of the right ventricle to hold its own with the return flow of blood and to re-direct it through the lungs where it is re-oxygenated before entering the left ventricle for completing the circulatory cycle. Usually secondary to failure of the left ventricle. May be caused by valvular disease, especially narrowing of the orifice of the mitral valve.

Mitral disease leads to heart failure either by a narrowing of the orifice (stenosis) or a regurgitation blocks the passage of blood from the left atrium (auricle) to the left ventricle. The left atrium enlarges (hypertrophies) in an effort to counter the impediment. Real compensation – increased thrust of the blood – is provided by the right ventricle. In order to overcome a mitral impediment the right ventricle has to enlarge.

Sooner or later the right ventricle cannot enlarge any further and general heart failure sets in. Though caused primarily by a lesion of the mitral valve, it may be secondary to left ventricular failure (LVF), thyroid disorder (thyrotoxicosis), pericarditis, congenital heart disease, or any disease which weakens ventricular muscle.

Venous congestion and back pressure of RVF leads to congestion and accumulation of fluid in the lungs, cough and spitting of blood, painful swelling of the liver, nausea, loss of appetite and severe wasting.

Where the right ventricle fails to move the blood forward as it arrives from the systemic circulation, generalised dropsy sets in. Congestion of the kidneys leads to reduced urinary excretion and presence of albumin in the urine.

The picture is well known to the cardiac practitioner: blueness of the skin, congestion of the brain circulation with sleeplessness and delirium. Soon the tension of water-logged tissues results in pain and extreme anxiety. Feet are swollen and ankles pit on pressure; chest cavities fill with fluid and the abdomen swells (ascites).

Alternatives. Cardio-tonics would be given to strengthen the ventricle and diuretics to correct fluid retention: Lily of the Valley, Hawthorn, Motherwort, Broom. BHP (1983).

Due to rheumatic fever: Hawthorn.

High Blood Pressure: Mistletoe.

Effort Syndrome: Motherwort.

Tinctures. Combine, Lily of the Valley 2; Hawthorn 2; Motherwort 3. Dose: 1 teaspoon thrice daily after meals.

Diet. Low salt, low fat, high fibre. Restricted fluids, vegetarian protein foods, yoghurt. See also: DIET – HEART AND CIRCULATION.

Supplements. Potassium (bananas), Vitamin B6.

General. Stop smoking. Correction of overweight. Complete bed-rest with legs raised above level of the abdomen and patient propped-up to relieve difficult breathing. ... heart – right ventricular failure (rvf)
