Cardiovascular technicians who obtain EKGs are known as electrocardiograph (or EKG) technicians. To take a basic EKG, which traces electrical impulses transmitted by the heart, technicians attach electrodes to the patient's chest, arms, and legs, and then manipulate switches on an EKG machine to obtain a reading. An EKG is printed out for ...
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
The Lifepak 1 was released the same year and was marketed as a more basic, but more compact model, lacking a cardiograph for ECG monitoring. In 1974, the Lifepak 4 was released with an integrated ECG recorder, and was followed by the Physio 260 (for home use) and Physio 1440 cardiac care system defibrillators were released to the public.

Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm. Cardiac monitoring is usually carried out using electrocardiography , which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram ...
The Holter's most common use is for monitoring ECG heart activity (electrocardiography or ECG). Its extended recording period is sometimes useful for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period. For patients having more transient symptoms, a cardiac event monitor which can be worn for a ...
The use of ECG can not only help diagnose cardiac problems but curve alterations can alert to electrolyte imbalances, hyper- and hypothyroidism, and varying central nervous system disorders. [ 57 ] Existing technology includes the traditional ECG machine that’s primarily used within a clinical setting and portable monitors that can be worn ...

The device is a small handheld single-channel ECG recording device that immediately sends information to a smartphone. Recordings can then be sent to a cardiac technician or a certified cardiologist for a small cost. [6] AliveCor obtains ECG traces through sensing plates, which can also be purchased through AliveCor.
