Ventricular tachycardias , especially incessant ones not controlled by drugs are very troublesome . Radio frequency ablation is the treatment of choice currently. Principles of electrophysiology would demand acccurate localisation of the tachycardia focus and then ablate it with RF energy .This requires induction of the clinical arrhythmia on the EP table, mapping , [...]

It is often said life is a cycle , time machine rolls without rest and reach the same point again and again . This is applicable for the knowledge cycle as well .
We live a life , which is infact a “fraction of a time”(<100years) when we consider the evolution of life in our planet [...]

Opening the chronically occluded coronary(CTO) artery gives the ultimate sense of achievement and satisfaction for the cardiologist. Of course , the patient may or may not share the same feeling . . . ! There are simple and complex CTOs . Some CTOs are opened in few minutes , some fail even after hours of [...]
Why ECG is greatly influenced by serum potasium levels and least affected by serum sodium levels?
Posted in Uncategorized on August 26, 2009 | Leave a Comment »
ECG is the summated recording of individual myocyte electrical activity from the body surface .The single cell action potential represent the classical description of ionic flows within and outside the cardiac myocyte. ECG is nothing but the electrical recording of systematic flow of ionic currents. When one looks at qrs complex we should mentally see [...]
Why UA/NSTEMI often occurs without wall motion defect ?
Posted in Uncategorized on August 25, 2009 | 1 Comment »
Regional wall motion defect is the sine qua non of STEMI. Whenever there is sudden occlusion of a coronary artery the segment , it supplies is expected to go in for mechanical dysfunction. This is the fundamental principle of ischemic cascade .But , in NSTEMI ,wall motion defects are not a consistent feature. In fact [...]

Do 64slice MDCT in all patients who has a coronary event and follow it up with catheter based CAG.
Use liberally the new biochemical marker , serum B-naturetic peptide (BNP) to diagnose cardiac failure in lieu of basal auscultation.
