Claim:
1. A method of monitoring and reporting premature ventricular contractions (PVCs) detected in a patient, the method comprising: monitoring an electro-cardiogram (ECG) signal of the patient with an adherent device that includes a plurality of electrodes; detecting premature ventricular contraction (PVC) beats based on the monitored ECG signal, and storing ECG episodes associated with detected PVC beats; calculating a morphology signal by quantifying the stored ECG episodes associated with detected PVC beats; numerically clustering the PVC beats based on the calculated morphology signals to group PVC beats having a similar morphology; generating an output that includes one or more of a total number of clusters generated, a count of the number of PVC beats included in each cluster, and a representative PVC beat from each cluster wherein calculating the morphology signal includes calculating a wavelet signal decomposition of the ECG episode associated with each detected PVC beat, and wherein calculating the wavelet signal decomposition of the ECG episode includes utilizing a linear combination of sub-band signals defined by equation s
