Terminal negative deflection of the P wave in lead V1 is produced by posteriorly directed depolarization of the left atrium. A value of more than 0.04 mm sec suggests increase in …
Three cases of the new appearance of ectopic supraventricular rhythms during exercise electrocardiography are presented. Transient decrease in the rate of the sinoatrial node or t…
A progressive and sustained decrease in systolic blood pressure on the continuation of exercise suggests severe left ventricular dysfunction irrespective of the cause. A transient…
We evaluated eighty one patients complaining of angina or angina equivalent symptoms on effort. Treadmill tests were performed using Bruce protocol. All confounding factors were e…
There is lack of consensus regarding regression equation to be used for calculation of age predicted maximal heart rate for evaluation of exercise stress test. We evaluated stage …
Previous studies evaluating heart rate recovery following treadmill test have significant limitations. We evaluated heart rate recovery pattern in ninety five normal individuals o…
There is no literature about different patterns of heart rate response during different stages of exercise stress electrocardiography using Bruce protocol in normal persons. We st…
Electrocardiographic changes on standing from supine position and subsequent hyperventilation were studied in 100 persons. Changes were correlated with any evidence of myocardial …
Several studies have tried to correlate heart rate profile during treadmill stress test with presence and severity of coronary artery disease and long term prognosis. These studie…
Hypertrophic obstructive cardiomyopathy localized to right ventricle is rare. There are no diagnostic clinical or electrocardiographic findings. Echocardiography is diagnostic. A c…
In spite of the incredible progress in human medicine, infectious diseases caused by bacteria, fungi, viruses and other parasites are still a major risk to public health. Since ag…
