Abstract:
Quantitative electrocardiogram (ECG) analysis is a very important tool in cardiovascular and neuroedocrine research. It is useful in clinical trials with human beings, as well as in animals such as rabbits, rats, and mice, for example, in studying knockout models. The species of interest differ in their typical baseline heart rate and therefore in the sampling rate in ECG detection. However, for obvious reasons, there are no available analysis programs adjusted to each species. We demonstrate how to use PhysioToolkit, an open source software developed by Massachusetts Institute of Technology for physiologic signal processing and analysis in humans, with murine ECG signals, with full control over analysis options. The procedure can be transferred on any other species in an analogue way.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
