you are 22 year old and the possibility of so called blockages is very very rare at this age. Not that they can never occur at this age but its rare. Secondly no of blockages cannot be determined by ECG. You have provided me the same ecg twice. The ECG shows a poor R wave progre...

An EKG performed in the clinic showed evidence of low voltage with poor progression of R wave [Fig. 1]. Echocardiogram was performed which showed an ejection fraction of 25-30%, severe left ventricular hypertrophy with involvement of septum greater than remaining segments, depressed right ...

A wide R wave with a notch on its top ("plateau") is seen in these leads. In hearts with an electrical (and anatomic) vertical position a small Q wave may be seen in AVL in the absence of MI. Right chest lead V1 may or may not show an initial r wave, but the latter should ...

A myriad of EKG changes have described as associated with heat stroke [25], [26] including sinus tachycardia, ST elevations, T wave inversions and QT prolongation. However, these changes are non-specific, seen with a number of other conditions and have been often attributed to accompanying elec...
