The His–Purkinje system constitutes a tiny fraction of the ventricular mass, but is specialized for rapid synchronous activation of both ventricles The pathogenic role of the Purkinje system is ...
Ventricular repolarization (VR) is a crucial step in cardiac electrical activity because it corresponds to a recovery period setting the stage for the next heart contraction. Small perturbations of ...
Darren Green, M.B.Ch.B.; Velislav Batchvarov, PH.D.; Chandrakumara Wijesekara, M.D.; Philip A. Kalra, M.D.; Alan J. Camm, M.D. There was a statistically significant ...
Repolarization dispersion has been linked to echocardiographic measures of diastolic dysfunction in past research, and a recent study found it potentially indicative of pulmonary arterial hypertension ...
The study results show that lower calcium and higher magnesium levels significantly prolong the time for the heart to contract and relax. The effect of lower calcium levels which 2% of the population ...
Background EKG analysis investigating the impact of the ethnicity on cardiac adaptation to exercise has shown a higher presence of abnormalities, including marked repolarization changes, and signs of ...
WHEN medical terminology was less precise the expression "strained heart" was employed at times to describe obscurely but ominously diseased hearts. This diagnosis is no longer made, but currently the ...
Left ventricular hypertrophy (LVH) is an abnormal thickening of the left ventricular myocardium that occurs as an adaptive mechanism to increased afterload. The left ventricular myocytes hypertrophy ...
