P morphology, P area and signal-averaged P wave late atrial potential are strong predictors of AF incidence and possibly of stroke incidence. ECG left ventricular hypertrophy is strongly ...

The most common ECG finding of an acute pulmonary embolism ... tachycardia occurs when every other beat has a different QRS morphology and each morphology meets VT criteria. This is caused most ...

This ECG shows a wide-complex tachycardia in a right bundle branch block pattern going quite fast (heart rate about 150 BPM). Note the morphology of the QRS complex in lead V6. There is a RS ...

Figure 18B shows the 12-lead ECG of the entrainment tracing of Figure 18A. The QRS morphology in all 12-lead ECGs during entrainment is identical to that of pacing in the absence of tachycardia as ...
