Why heart palpitations after new pacemaker

Clinical symptoms of pacemaker malfunction are variable and include syncope, dizziness, palpitations, and slow or fast heart rate . Extracardiac stimulation or hiccough may be present. Obtain as much information as possible regarding the pulse generator, leads, and programmed values.

Pacemakers can also relieve some afib symptoms. “You’ll no longer feel a racing heartbeat,” says Dr. Pershad. Dizziness, shortness of breath , and general fatigue may also be eased.

A pacemaker is sometimes used to correct slow or irregular heartbeats called arrhythmias . These arrhythmias may cause you to feel light-headed, breathless or even experience black-outs. If your heart rate is too slow, the pacemaker will send an electrical signal to the heart muscle to start a heartbeat.
