What's the source of the unusual electrocardiogram (ECG) findings in a patient presenting with dizziness and limb weakness? That's the mystery posed in a recent case report. The diagnostic challenge ...

Not all atrial flutters demonstrate the typical "sawtooth" pattern. During the times of lesser conduction on this ECG, the flutter waves are more apparent. The atrial rate is organized at a rate of ...

At times it is difficult to distinguish atrial fibrillation from atrial flutter on the ECG. This example shows coarse "fibrillatory waves" in the setting of atrial fibrillation. This are of varying ...

The rhythm in Figure 1 has a subtle pattern—a narrow QRS complex with alternating short and long R-R intervals, resulting in paired QRS complexes. Careful observation of V1 in Figure 2 reveals tiny ...

The QRS complexes are narrow and have a normal morphology. The axis is physiologically leftward with a positive QRS complex in lead I and II, and negative in lead aVF. The QRS complex voltage is low ...

A new method of evaluating irregular heartbeats outperformed the approach that's currently used widely in stroke units to detect instances of atrial fibrillation. The technology, called ...

Objective A systematic review, meta-analysis and meta-regression were performed on selected studies to investigate the incidence of atrial fibrillation (AF) among athletes compared with non-athlete ...

It's important to determine whether stroke patients also experience atrial fibrillation (Afib). Monitoring technology could make the process easier and more accurate. A new method of evaluating ...

Tikosyn (dofetilide) is a brand-name drug prescribed for atrial fibrillation (AFib) and atrial flutter in adults. Tikosyn comes as an oral capsule that’s typically taken twice per day. The dosage can ...

With heart rate monitors now standard in smartwatches and fitness trackers, electrocardiograms (ECG/EKG) have rapidly become a common feature in health wearables. The technology aims to assist ...
