Artifacts resembling ventricular tachycardia and fibrillation Artifacts in an ECG can mimic various pathological conditions. In V1, multiple small artefacts almost totally obscure the small QRS complexes so

Deep T inversion First few conditions which come to our mind when we see deep T wave inversions are: Coronary artery disease Hypertrophic cardiomyopathy Post cardiac arrest state

Inferolateral myocardial infarction ST segment elevation is seen in inferolateral leads (II, III, aVF, V5, V6) indicating inferolateral ST elevation myocardial infarction (STEMI). There is a discordance between

Right bundle branch block with right upper quadrant axis ECG demonstrating right bundle branch block with right upper quadrant axis: rsR’ pattern in V1, rS pattern in I,

Tall peaked T waves Tall peaked T waves are seen in leads V2-V4 (C2-C4). In addition there is prominent negative component for P wave in lead V1 (C1)

Treadmill Exercise ECG, also known as treadmill test (TMT) and stress ECG is usually done with a computerised treadmill unit which controls the motor speed of the treadmill

Very long pause noted on ICU monitor Very long pause noted on ICU monitor (central monitor) of about 8 seconds and two more pauses of around 2 seconds

Detection of myocardial infarction in paced rhythm Detection of myocardial infarction in paced rhythm is often difficult due to the baseline abnormality in depolarization and secondary abnormality in

AV sequential pacing (tracking) At a glance this will seem to be a simple LBBB (left bundle branch block. But the QRS complexes are negative in V5, V6

Paced rhythm with retrograde P waves Paced rhythm with retrograde P waves: ECG shows a wide QRS rhythm with LBBB pattern in I, aVL and V1. Axis is
