Question

In the past, an irregular heart rhythm was treated by using a drug to help regulate the beat. There is a treatment that can also regulate heart rhythms that has replaced drugs in some cases. What is that treatment?
A. pacemaker

B. angioplasty

C. clot-dissolving drugs

D. myocardial infarction

Answer 1

The pacemakers are implants that are used for the regulation of heartbeats (correction of irregular heartbeats).

It is a small device, implanted (minor surgical procedure) just under the skin of the chest, that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm.

 

The pacemaker has two parts:

·         the leads which are threaded through the veins into the heart and implanted into the heart muscle. They send impulses from the pulse generator to the heart muscle. There can be one or more leads depending on the type of the heart problem

·         a pulse generator which contains the battery and a tiny computer and resides just under the skin of the chest.

Each impulse causes the heart to contract. A pacemaker may also be used to treat different heart issues such as fainting spells (syncope), congestive heart failure, and hypertrophic cardiomyopathy.

Answer 2

Despite the fact that prescription drugs were used in the past to treat irregular heart rhythm, advances in medical science now allow the pacemaker to be implemented into the heart in order to more safely regulate heart rhythms for those with irregular beats.
