What Causes Lower Heart Rate?

You might have experienced a racing or fast heart rate during exercise, adventure activities or in anxious situations.

In contrast, a slow heart rate also known as bradycardia occurs at 60 beats per minute (bpm) or less.

It might occur even when active, as your body responds positively to exercise.

However, low heart rate might occur due to a malfunction in its natural pacemaker, the heart’s sinus node.

Conditions such as atrioventricular block, age, and inflammation of the heart muscle might result in lower heart rate as well.

Electrolyte deficiencies, especially when your body does not get certain electrolytes like calcium, magnesium and potassium can result in lower heart rate.

Monitor your heart rate, breathing rate, strain, heart rhythms, HRV, continuous ECG and a lot more using Frontier X2.
