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 ...

In the present study, our first aim was to assess the capability of body surface potential mapping (BSPM) QRS area analysis for detection and quantification of pressure overload-induced LVH compared ...

A narrow QRS tachycardia at a rate of 105 beats/min. is present. No P waves are identified in front of the QRS complexes, suggesting accelerated AV junctional rhythm. However, there are two PVCs.
