Bainbridge Reflex Bainbridge Reflex was described over a century back, in 1918 as the influence of venous filling on the heart rate [1]. It was noted as an
Localisation of Ventricular Tachycardia by Surface ECG Surface ECG can be used to identify the site of origin of ventricular tachycardia. QRS morphologic patterns and vectors are helpful
Myocardial Ischemia-Reperfusion Injury Myocardial Ischemia-Reperfusion Injury is a paradoxical exacerbation of cellular dysfunction and cell death occurring after restoration of blood supply in previously ischemic tissues. Reperfusion of
Non-Left Main Bifurcation Lesion PCI Strategies Bifurcation lesions may be noted in almost one third of cases for percutaneous coronary intervention. Outcomes for bifurcation lesions are worse compared
Naming of components of QRS complex Initial negative deflection of the QRS complex is named a q or Q wave depending on the amplitude. Usually waves less than
Coronary Angioplasty Initial part of the video clip shows left coronary angiogram with total occlusion of left anterior descending coronary artery. Annotations are given in still frames in
Normal Colour Doppler Echocardiogram in Multiple Views Starting from the two dimensional parasternal long axis view, followed by colour flow mapping, M-Mode at chordal level, parasternal short axis
Regional wall motion abnormalities in LAD territory on echocardiography. Echocardiography is one of the simplest investigations to assess the myocardial regional wall motion abnormalities in coronary artery disease.
Epsilon Wave Epsilon wave, the classical ECG finding in arrhythmogenic right ventricular dysplasia is seen at the end of the QRS complex. Epsilon wave is typically seen in
Compliant vs noncompliant balloon catheters Compliant balloon will increase in diameter as the pressure in the indeflator increases, as the name implies. They are made of polyurethane or
