Abstract: An electrocardiogram (ECG) acquisition and viewing system receiving extended ECG recordings and automatically extracting segments with heart arrhythmias allowing overreading cardiologists to quickly analyze the extract segments from the larger data set. The present invention provides an easy to use, lightweight ECG module providing acquisition of 12 lead ECG data and communication with local and remote network devices receiving the ECG data The present invention provides wireless communication (e.g., Bluetooth, near field communication) with local devices so that ECG waveforms may be viewed in real time, allowing lead connections to be corrected and integrity restored before and during data acquisition.
