Circulation: Heart, cardiac cycle, blood pressure

Myocardial contractility or force of contraction represents the heart muscle, myocardium, or cardiac muscle’s inherent capability.  There exists a gradational level of irrevocability within various kinds of tissue. An example is the binding between the filaments of thick myosin and the thin actin tissue. This irrevocability results in the ability to develop changes in the […]

Cardiac output is the volume of blood pumped out by both heart ventricles per minute, between 70-72 per minute. Cardiac output or heart output is denoted by the letter Q or Qc. The volume of blood is also called stroke volume. The measure of cardiac output holds excellent clinical significance in medical science to diagnose

An electrocardiogram, often known as an ECG, is a test that detects and records the intensity and timing of electrical activity in the heart. This information is shown on a graph, which illustrates each phase of the electrical signal as it travels through your heart. The electrical signal begins in the sinoatrial node (1) of the

About ECG The electrical signals in your heart are recorded by an electrocardiogram. It’s a simple and painless test for detecting cardiac problems and keeping track of your heart’s health. Electrocardiograms (ECGs or EKGs) are commonly performed in a clinic or hospital room. In operating rooms and ambulances, ECG machines are commonplace. ECG monitoring is

Our heart is the most delicate and vital organ that keeps us functioning. This muscular organ is just the size of an average fist. It is the main regulator of the cardiovascular system of the body. You must already know the basics of how it pumps blood connecting with a set of veins and arteries.

Coagulation illnesses affect the body’s ability to form blood clots, resulting in either too few or too many clots, which can be harmful. Some coagulation issues are inherited, which means they run in families. They can, however, be acquired at any time during one’s life as a result of certain therapies or medical conditions. Anyone

Hypertensive heart disease is characterised by structural and functional abnormalities in the left ventricle, left atrium, and coronary arteries as a result of persistent blood pressure elevation, which increases the workload on the heart. Hypertensive heart disease is caused by chronically high blood pressure (greater than 120/80 mmHg). High blood pressure puts a load on

Uremia is a clinical term that refers to a condition that is characterised by bilateral renal insufficiency and nitrogen retention. While the symptoms and findings may be numerous and different, the clinical picture typically includes varying degrees of headache, vomiting, pericarditis, gastrointestinal problems, and, in the late stages, coma and death. Laboratory findings include an

Angiotensin plays a vital role in regulating and maintaining the level of blood pressure in the bloodstream and also affects the fluidity level in the body. There are other hormones that increase and decrease the production of angiotensin hormone in the body.  Overview Angiotensin is a chemical compound found in the body. It comes under

Coronary artery disease is defined as the buildup of plaque in the arteries that supply oxygen-rich blood to your heart. Plaque causes constriction or blockage of the arteries, which can lead to a heart attack. Common symptoms include chest pain or discomfort, as well as shortness of breath. Dietary modifications, medications to address your risk
