The length of the PR interval falls on top of the T waves (↓ on Figure 2), indicating that the P waves are superimposed on the T waves and proving the rhythm to be sinus tachycardia with ...

This is a challenging ECG in regards to determining if the wide QRS complex rhythm is from ventricular tachycardia or "SVT with aberrancy" such as AV nodal reentry tachycardia causing a rate ...

Studies over a 24-hour period have also shown that more frequent PVCs — recorded in this way — are also linked to an increased risk of heart failure and heart-related deaths, but the risk is greater ...

Well, an EKG is really the first test we look for in patients with symptoms of palpitations. Palpitations mean different things to different patients. You may mean a quickening of the heart rate ...

Among ECG parameters, QT and QTc intervals and QTd were more prolonged in pre-eclamptic women. Multivariate analysis also showed that pre-eclampsia was the only independent determinant of QTd.

I went into my patient portal and reviewed the EKG, and to my surprise, it stated that there was an infarction in the septum.

However, during the compensatory pauses after the PVCs (↑) in tracing "b," there are regular atrial activities at a rate close to 300 beats/min, proving that the rhythm is atrial flutter (Figure 2).
