The Evolution of Pacemakers

3:27:00 AM Rajesh singh 0 Comments



A pacemaker is an electrically-charged medical device used to stimulate the muscles of the heart and regulate its contractions. It helps to manage irregular heartbeats, known as arrhythmias. One part of the device is called the pulse generator, which contains the electronics and battery, both of which that control the heartbeat. The second part is one or more leads, which send electricals signals to the heart.

Pacemakers have come a long way since the first prototype that was invented almost 100 years ago.

The history of pacemakers

The very first pacemaker in history was invented by American physiologist Albert Hyman and Australian anesthesiologist Mark Lidwell in 1928. The device was designed to restore the patient’s normal heartbeats if they stopped. It was made up of a big current-generating motor, which was hand-wound, and a bipolar needle. This needle encompassed both positive and negative electrodes.

Canadian electrical engineer John Hopps invented the first portable pacemaker in the early 1950s. It was a bulky external unit and delivered electricity through a flexible bipolar catheter. This catheter was inserted into the right atrium of the heart via a vein. With the help of this, the patients’ heart rates could be controlled without chest contractions.

Between the late 1950s and early 1960s, many innovative breakthroughs were accomplished that led to the wearable pacemaker, which was battery-operated. It was invented by the electrical engineer Earl E. Bakken.It worked on the rhythmic output of electronic metronomes. The power supply lasted 1000 hours. This innovation improved the mobility and size of pacemakers.Therefore, patients could wear them strapped to the body or on the neck.

After Bakken’s development, physician Rune Elmqvist and Swedish surgeon and engineer Ake Senning developed the first implantable pacemaker. It was the size of a Kiwi shoe polish can.It was made using silicon transistors, which considerably lowered the energy required to make the pacemaker operate.

Since then, implantable pacemakers have become a modern innovation. They have become more streamlined, efficient, and effective in helping patients live a better life.

Modern pacemakers

Modern pacemakers weigh less than one ounce and are slightly bigger than the face of a wristwatch. They are capable of pacing heartbeats via electric currents and can also help monitor a patient’s natural electrical activity in the heart. With a surgical procedure, the pacemaker is implanted into a pocket under the skin just below the collarbone. This procedure takes not more than two hours.

The future of pacemakers

Pacemakers are aiming to become long-term solutions to arrhythmia. Downsides of modern pacemakers include low battery life. Usually, a pacemaker’s battery lasts anywhere between five to seven years. This is one of the problems that research and technological innovation will try to improve upon in the coming years. Another issue is the price, as pacemakers can be expensive.

Pacemakers and critical illnesses

A heart condition, which necessitates a pacemaker, may fall into the category of a critical illness. A critical illness is a health condition that can have a debilitating impact on a person’s lifestyle. A critical illness insurance policy may help you cover treatment expenses for such a condition when a pacemaker is required. It is advisable to go online and check critical illness insurance comparison tables to determine which provider offers such a cover.
