== BEGIN QUOTE ==

Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity, generally by electrocardiography, with assessment of the patient's condition relative to their cardiac rhythm. It is different from hemodynamic monitoring, which monitors the pressure and flow of blood within the cardiovascular system. The two may be performed simultaneously on critical heart patients. Cardiac monitoring with a small device worn by an ambulatory patient (one well enough to walk around) is known as ambulatory electrocardiography (such as with a Holter monitor, wireless ambulatory ECG, or an implantable loop recorder). Transmitting data from a monitor to a distant monitoring station is known as telemetry or biotelemetry.

What is a cardiac monitor?
A cardiac monitor, also known as a heart monitor, is a device that allows for the continuous monitoring of the heart’s activity through electrocardiography (ECG/EKG). Outside of the doctor’s office, heart monitoring is done with an ambulatory cardiac monitor that a patient will wear home with them. This allows for a doctor to observe how their patient’s heart is functioning over an extended period of time in order to diagnose conditions related to irregular cardiac rhythms.

What is an event monitor?
An event monitor and a Holter monitor are similar in that they are used to remotely record heart irregularities to aid in the diagnosis of cardiac conditions by measuring the heart’s electrical activity. However, an event monitor does not record the heart’s ECG continuously. The recording is initiated by the user, usually when the patient is experiencing symptoms. This is the main disadvantage of an event record over a continuous ECG monitor, as it does not capture events that occur without symptoms. This has the potential to lead to missed diagnosis.

What is the difference between an event monitor and a Holter monitor? Which one is better?
A Holter monitor records the heart’s behaviour continuously whereas event recorder records short periods only and the start of the recording must be initiated by the user. For that reason, an event recorder is considered less effective as many heart problems are without symptoms and occur sporadically. If the user is not experiencing any symptoms, these might be missed with an event recorder.

While a Holter monitor will provide a more complete picture of heart activity necessary for the diagnosis of cardiac conditions, there are still quite a few disadvantages. Holter monitors are typically found to be cumbersome and uncomfortable, requiring skin preparation, patches, and wires. We have created a better alternative for continuous heart monitoring in QardioCore, wireless medical-grade ECG monitor.
