Wide QRS regular tachycardia is present in Figure 1. No definite P waves are identifiable. There is one PVC in the lower tracing. During the compensatory pause, there is definitely a P wave (↓ on ...
Left ventricular hypertrophy can be diagnosed on ECG with good specificity. When the myocardium is hypertrophied, there is a larger mass of myocardium for electrical activation to pass through; thus ...
A premature ventricular contraction occurs when a focus in the ventricle generates an action potential before the next scheduled sinoatrial nodal action potential. Ventricular bigeminy occurs when ...
