I have a pacemaker for more than 4 years and have checked it every 6 months, the doctor said the battery has 12 years left, but why now suddenly my heart rate drops to 41, making me dizzy, then I take a deep breath to get the rhythm The heart rate stabilized as at 60 beats/min. In 1 hour I got it about 3 times. Is this situation caused by the machine or what, doctor? So the doctor asked me to put on a pacemaker but my heart rate decreased, what should I do? Thank you doctor.
