Abnormal Heart Rhythms (Arrhythmias)
Each year millions of people experience abnormal heart rhythms (arrhythmias), which are common as we age. For most, a normal resting heart rate is 60 to 100 beats per minute (bpm). For athletic individuals, a normal resting heart rate may be as low as 40 to 60 bpm.

A person with myoclonus experiences sudden, involuntary lightning jerks. Myoclonus may develop in response to various conditions, including prolonged oxygen deprivation to the brain, infection, head or spinal cord injury, stroke or brain tumors.
