Small, wireless skin patches may offer a convenient way to diagnose—or rule out—arrhythmias.

An abnormal heart rhythm—when your heartbeat is too slow, too fast, or irregular—may be a fleeting, harmless event. But it might be a sign of a more serious heart condition. If you have frequent palpitations (which feel like your heart is pounding, racing, or fluttering) or unexplained fainting spells, your doctor may recommend a Holter monitor. This portable electrocardiogram (ECG) machine records your heart rhythm over a day or two.

Q. I have a pacemaker and was told to never have an MRI scan. Is there any way around that?

A recent study in Annals of Internal Medicine suggests that people with mild high blood pressure and no symptoms of heart disease can still benefit from taking blood pressure medication.

When your blood pressure tips above 140/90 mm Hg, most doctors suggest medication—in addition to healthy diet and exercise. The higher your blood pressure, the greater the risk of heart attacks, strokes, and death. What experts disagree on is how low you should shoot for once your blood pressure is clearly above the 140/90 threshold.
