Development of Cardiac Implantable Electrical Devices

Rakesh Gopinathannair, and Brian Olshansky

Introduction

A remarkable collaborative and forward-thinking effort led to the development of cardiac implantable electrical devices (CIEDs), which can stimulate the heart to beat, protect against cardiac arrest, monitor physiologic parameters and arrhythmias, and improve and forestall heart failure. Some key events that led to modern CIEDs and their implantation are described here with a look toward the future.

Where Did It Start?

Myths and science converge in the initial attempts at cardiac stimulation. The rather dubious beginnings are hard to establish precisely, considering the naivety regarding mechanisms and lack of documentation and peer review. Initial observations occurred before electricity was understood fully and before wall power. Nevertheless, cardiac stimulation began hundreds of years ago, if not long before that, first mechanically, then electrically.

William Harvey made an arrested pigeon’s heart beat with the flick of a finger.^1–3 Physicist Nickolev Abildgaard realized that electrical shocks could cause a hen to collapse but additional shocks brought it “back to life.”⁴ By the 1900s, electrical currents were seen to start and stop ventricular fibrillation.⁵ Rudimentary electrical resuscitative device attempts for ambulances, however, initially met with little success.

Birth of the Pacemaker

Astounding observations lent credence to the concept that electricity affected the heart (Table 1.1). In one instance, a child who drowned was resuscitated by attaching one electrode to the leg while rhythmically tapping the heart with another (Duchenne de Boulogne, 1806–1875). Why this was attempted is not clear. In another instance, electrical cardiac stimulation was seen to affect heart rate directly in a woman who had a chest tumor removed, leaving her heart exposed (H. von Ziemssen, 1829–1902). Unfortunately, stimulation attempts may have resulted in her death.

In 1889, John Alexander McWilliam reported brilliant work that showed electrical impulses could cause ventricular contraction (Fig. 1.1). He stated:

The heart was inhibited by stimulation of the vagus nerve in the neck, and then a periodic series of induction shocks (regulated by a metronome) was applied to the apex of the ventricles.… A series of single induction shocks excites a corresponding series of cardiac beats; the ventricular contraction precedes the auricular contraction when the exciting shocks are applied to the ventricles. Each systole causes the ejection of a considerable amount of blood into the aorta and pulmonary artery, and a marked rise of the blood-pressure at each beat.⁶

Although early experiences were not uniformly successful, by 1927, Marmrostein had found a way to electrically stimulate a dog’s heart.⁷ Soon thereafter, human cardiac pacing emerged. Mark Lidwell, an Australian physician, is considered one of the fathers of modern pacing. In 1928, with alternating current and a needle inserted into a ventricle, he used intermittent electrical stimulation to resuscitate a child born with a cardiac arrest.⁸ To extend these initial observations, in 1932, Albert Hyman, a cardiologist working at the Beth David Hospital in New York, utilized a needle he called a “pace-maker” to create an injury current in the heart (“intracardiac” therapy) to allow it to beat again. In collaboration with his engineer brother, C. Henry Hyman, he developed a spring-wound, hand-cranked stimulating motor he called an “artificial pacemaker.”² The mechanism was simple, but it worked and was used 43 times with success in 14 patients (Fig. 1.2). Based on the need for increasing heart rates during hypothermic procedures, Wilfred Bigelow, working with John A. Hopps, an electrical engineer, developed a transvenous catheter electrode that was placed in the heart and activated using an external stimulator.¹

Further development halted for quite some time when, in 1951, Boston cardiologist Paul Zoll developed an external (transcutaneous) pacemaker that could stimulate the heart but required 50 to 150 V of alternating current delivered via external metal electrodes strapped to the chest (Fig. 1.3). It was painful and caused skin burns. The longest period of pacing with his system was approximately 11 days, but his initial work became a starting point for development of the implantable pacemaker. Aubrey Leatham and Geoffrey Davies improved Zoll’s transcutaneous stimulator by developing circuitry that could sense the electrocardiogram and pace only when needed. It had a fixed rate and two output ranges, thus creating the first “demand” pacemaker.⁹

C. Walton Lillehei found that a pacemaker, attached with a wire electrode directly placed in a dog’s heart, could stimulate at lower voltages and with shorter pulse widths. In January 1957, a 3-year-old girl, who had developed complete heart block after open-heart surgery to correct a congenital defect, was paced using the Lillehei system and ultima...
