Overview

InstantCheck is a handheld ECG monitor that records and displays a real-time electrocardiogram (ECG). ECG can be recorded by placing the thumbs on InstantCheck's specially designed dry contact built in electrodes or by using the external electrode cable and adhesive ECG electrode pads. Unlike other devices there is no need to place the InstantCheck directly on the chest a major advantage.

InstantCheck records 100 thirty seconds strips of modified lead one ECG for each measurement. After measurement, the device will instantly display the average of 3 parameters on the LCD panel: the average heart rate (HR), ST segment and QRS intervals. ECG trace can be reviewed directly on the LCD panel. It also include scalable ECG function (x2).

InstantCheck is especially useful for the opportunistic screening of atrial fibrillation (AF) in Primary Care and a recent study suggest that opportunistic screening for atrial fibrillation (AF) in routine appointments could vastly improve its detection in general practice BMJ ( 2 August 2007 335-383)

AF affects approximately 5 per cent of people over the age of 65 years. The risk of serious outcomes, such as stroke, can be reduced by treatment, so the diagnosis of AF is important in primary care.

InstantCheck is suitable for use by patients at home who may have intermittent arrhythmias that do not present in surgery after a 12 lead ECG, for opportunistic screening of AF and for long term cardiac evaluation to monitor the effectiveness of anti-arrhythmic drugs. They can be loaned an InstantCheck and can record their ECG when symptoms occur or to measure at regular intervals to assess circadian influences.

The InstantCheck can also be used as a non-invasive device if patients refuse to have an implantable event recorder.

Important Information- InstantCheck is a screening device only and is not designed or intended to replace a medical diagnosis from a qualified medical professional. The measurement results are for monitoring purposes only and should not be used as a basis for starting or modifying medical treatment without independent medical advice. The InstantCheck is not designed or intended to be used in acute or critical situations.

This device should not be used with a cardiac pacemaker or defibrillator.
