This ECG demonstrates the typical "reverse check" or "reverse tick" sign seen in the setting of digoxin therapy. Atrial fibrillation with a slow ventricular response is one of the more common ...

This next generation model will sport FDA-approved atrial fibrillation (aFib) detection and will be one of the thinnest (if not thinnest) finger wearables yet, although that comes at the expense ...
