Overview
Brief Summary
The 12-lead ECG is an essential tool in cardiovascular assessment. Novel technology has the potential to improve the diagnostic yield of arrhythmias, whilst improving the patient experience.
The RhythmPadGP is a novel device which acquires a 6-lead ECG without the need for the patient to undress.
The aim of the study is to assess the ability of the device to diagnose cardiac rhythms.
Simultaneous recording of the RhythmPadGP 6-lead ECG will be undertaken at the same time as the standard 12-lead ECG.
The 12-lead ECGs and 6-lead ECGs will be analysed by a Cardiologist, who will be blinded to each set of ECGs and the automated diagnostic report produced by the RhythmPadGP device.
Such a novel diagnostic tool could replace the standard 12-lead ECG for rapid assessment and diagnosis of arrhythmias. Additionally, as calls for a national screening programme to detect atrial fibrillation (and prevent AF-related thromboembolism) currently intensify, the RhythmPad has the potential to revolutionise how we screen our patients.
Detailed Description
The concept for the Rhythm Pad is to screen the public non-invasively for a cardiac rhythm abnormality, every time that they interact with a clinician. Cardiocity have conducted significant trialing of the RhythmPad product within both the primary care setting at the Old Cottage Hospital in Epsom and in a secondary care setting at St Peter's Hospital in Chertsey. The initial results were encouraging with a simple hand screening providing an indication of AF in 66% of the confirmed cases of AF, when verified by a traditional electrocardiogram (ECG) known as a GE MAC550 12 lead device as the benchmark. The main aim is for the RhythmPad range of products to increase the ability to diagnose cardiac rhythm abnormalities, along with reducing the number of false positive referrals to secondary care for a 12 lead Electrocardiogram of ECG. As such confirming the diagnosis before referral reduces the number of false positive referrals. If one of our algorithms thinks that there is evidence that the person might be in a state of Atrial Fibrillation (AF), Flutter, might have left or right bundle branch block, etc, then by moving to the 6 lead we are able to increase the confidence of the diagnosis. The RhythmPad is now able to support a 6 lead ECG acquisition, this is by using a modified device called the RhythmPadGP as such we would plan to trial this technology with St Peter's Hospital. We have learnt from the experiences of the previous trails. We know that 5% of the entire population will not have strong enough Lead 1 ECG when measured from their hands. Also those with Essential Tremor, Parkinson's etc. are not able to keep their hands steady for an accurate reading to be taken. In such cases, or as an escalation from the one lead data, we now offer through a simple Velcro ankle strap attachment the ability to record 6 leads of data.
