i have delt with thousands of patients with a slow heart rate(bradycardia
) and it most cases it causes no inconvenience to the person life style or health,, there is simple medication available that will encourage the heart to pump at a normal rate..
a pace maker is a last resort for most patients and usually for the over forties..
having said that a lot depends on what is causing the problem and how slow is the heartbeat.... a heart beat of 60-80 pm is normal for a adult at rest but some athletic people have a heart rate of 40 bpm at rest
the heart is a complex organ and has many safety features built into it,, the initial beat comes from the s.a node at the top of the right atrium
and sends a signal via the punjibe fibres to encourage the ventricles (lower heart chambers)to contract and pump the blood through the body,, however if the sa. node fails for any reason the heart can fire of the signal to beat at two lower locations and get the same result,, poss this is where your friends missing beat comes into play,, im sure her doctor will do what is required and you try not to worry about your friend im sure she will be fine ... keep smiling
