Topics include diagnosing ventricular tachycardia with capture beats, the interpretation of QRS complex patterns; and the importance of distinguishing between various arrhythmias in clinical evaluation.doi:10.1093/ehjcr/ytae392Jeewooth AvinashKaushik AtulJaswal AparnaEuropean Heart Journal - ...
Intrinsic sinus node dysfunction cannot be excluded entirely in our case; however, complete resolution of the ECG abnormalities with the hyperkalemia treatment and normalization of serum potassium levels suggests hyperkalemia as the most likely etiology. In hyperkalemia, the increased extracellular potassium...
The points of the ventricular complexes vary in their height, appearing to turn around a central axis, the baseline of the ECG tracing. It is important to measure the QT interval. QT prolongation can be caused by electrolyte disturbances, antiarrhythmic drugs, or central nervous system or...
ECG criteriathe QRS complex is wide and often premature with increased amplitude and of a bizarre shape. the QRS width is 0.12 second or wider. the T wave is of opposite polarity to QRS complex. there is no related P wave (unless there is retrograde conduction back through the AV node, ...

PVCs are said to be “frequent” if there are more than 5 PVCs per minute on the routine ECG, or more than 10-30 per hour during ambulatory monitoring. How many PVCs in a row is Vtach? Three or more PVCs in a row at what would be a rate of over 100 beats per minute is called...
An ECG can help diagnose which of the following conditions? a. low hemoglobin b. high blood pressure c. arrhythmias d. high after load on the heart Determine whether the following is a clinical sign generally seen with pheochromocytoma or not: Tachycardia. Fill in the blanks with...

However, after careful analysis of the ECG, a diagnosis of Wolff-Parkinson- White (WPW) syndrome was made with a short PR interval and slurring of the upstroke of the QRS complex (delta wave, fig 1). She was scheduled for an electrophysiological study and ablation, but the procedure ...
A 33-year-old woman presented to emergency department with palpitations. Her initial rhythm strips were interpreted as first-degree AV block and bigeminy premature ventricular contractions. However, after careful analysis of the ECG, a diagnosis of Wolff-Parkinson- White (WPW)O...
