PQRST in ECG The waves and intervals in a normal ECG are illustrated here. P wave is due to atrial depolarisation. QRS is the ventricular depolarisation and T

Left ventricular hypertrophy Left ventricular hypertrophy is manifest in this ECG as tall R waves in lateral leads (leads I, aVl, V5 and V6). S wave in V1

Atrial Fibrillation with Bigeminal Rhythm Baseline is irregular and lead V1 shows coarse fibrillary waves suggestive of atrial fibrillation. But the unusual feature about this ECG is the

Heart disease in mice reversed Tiny fragments of genetic material may play a great role in the development of heart disease. By modifying the genetic material, scientists have

64 slice CT accurately predicts presence and severity of coronary artery disease 64 slice CT angiography accurately predicts presence and severity of coronary artery disease, says a recent

How is embolisation of an artery done? First an angiogram is done by injecting the main artery with iodinated contrast to visualise the origin of the target vessel from

What is long QT and how can it be recognized? QT interval represents the electrical repolarisation of the heart. It is measured from an ECG. A long QT

Treadmill test (TMT) Treadmill test (TMT) or exercise stress test is one of the commonest forms of stress tests used to induce provokable myocardial ischemia for diagnostic evaluation

Hormone replacement patches found to decrease heart disease risk Hormone replacement patches were found to decrease risk for heart disease upto 40%. Women tend to have a lower risk
