A proposal for monitoring patients with heart failure via “smart phone technology”-based electrocardiograms

The ubiquitous smart phone/device technology (SPT) has enabled the safe acquisition/transmission (A/T) of clinical and laboratory patient data, including the electrocardiogram (ECG). SPT-based A/T of the ECG has been found useful in the detection of atrial fibrillation, in monitoring of the QTc interval, in patients undergoing antiarrhythmic drug loading, and in management of patients with acute ST-elevation myocardial infarction. Previous work has shown a relationship between changes in the voltage of the ECG QRS complexes, with perturbations in the edematous state of various etiologies, including heart failure (HF). It is proposed herein to employ serially SPT-based 3-lead ECG A/T for the monitoring and management of patients with HF in their ambient environment. The proposed method will enable patients with HF to acquire/transmit their 3-lead ECG to the caring HF team, using only their smart phone and it takes into consideration the advanced degrees of physical incapacitation and age-related infirmities inherent to the HF population.
