Coronary steal The term ‘coronary steal’ (CS) is basically diversion of coronary flow from one artery to another. It can be either between from one coronary territory to
Reverse pulsus paradoxus Reverse pulsus paradoxus is an expiratory fall in pulse volume, the opposite of pulsus paradoxus. The classical causes of reverse pulsus paradoxus described are [1]:
Pulsus paradoxus Pulsus paradoxus is the exaggeration of inspiratory fall in pulse volume and in an extreme case the pulse may disappear in inspiration (pulsus paradoxus totalis). The
Diastolic pulsus alternans Though there is no pulse felt in diastole, diastolic pulsus alternans (DPA) has been described as the alternation of mitral inflow velocities. In one case
Biventricular pulsus alternans (BVPA) Pulsus alternans is alternating volume of pulse, with a regular rhythm, mostly seen with severe left ventricular dysfunction. Biventricular and right ventricular pulsus alternans
Total pulsus alternans – pulsus alternans totalis Total pulsus alternans or pulsus alternans totalis occurs when the force of contraction is so low in alternating beats that the
Traube’s pulse – pulsus alternans Pulsus alternans or Traube’s pulse was described by Ludwig Traube in 1872 [1]. Traube’s pulse is nothing but alternating pulses having different volumes and
Atrial septal defect with right to left shunt should prompt us to look for total anomalous pulmonary venous connection as well as severe pulmonary hypertension.
ECG chest lead positions Positioning chest leads in wrong locations is quite common, often due to difficulty in locating anatomical landmarks, especially in females. V in chest leads
