An electrocardiogram (ECG) is a graphical recording of the changes occurring in the electrical potentials between different sites on the skin as a result of cardiac activity. The electrical activity of the heart is a sequence of depolarizations and repolarizations. Depolarization occurs when the cardiac cells, which are electrically polarized, lose their internal negativity. The spread of depolarization travels from cell to cell, producing a wave of depolarization across the entire heart. This wave represents a flow of electricity that can be detected by electrodes placed on the surface of the body. Once depolarization is complete, the cardiac cells are restored to their resting potential, a process called repolarization.
This flow of energy takes on the form of the ECG wave and is characterized by an initial P wave, followed by the QRS complex, and then the T wave. The P wave is associated with depolarization of the atria, the QRS complex is associated with depolarization of the ventricles, and the T wave with repolarization of the ventricles.
This application note is designed to assist with the advanced analysis of ECG data, specifically P, Q, R, S and T Wave analysis. This Application Note describes how to set up the Biopac Student Lab software to find R time, R height, Rate, Inter-Beat Interval, S height, P height, Q height, and T height and how to place your measurements into the journal.
Cardiovascular Hemodynamics - Hardware for human and animals. Measure continuous BP, ECG, stroke volume, cardiac output, PPG, etc. For animal and tissue look at acute and chronic dose-response.
Remote Monitoring - BioNomadix modules provide high quality, full-bandwidth data for a variety of signals—ECG, EEG, EGG, EMG, EOG, PPG, RSP, SKT, Accelerometry, Cardiac Output, Dynamometry, and Heel-Toe Strike.
BIOPAC is introducing Biopac Student Lab Home (BSL HOME)—a new product specifically geared towards teaching physiology labs remotely so students can still get hands-on, practical lab experience if social distancing and stay-at-home orders keep them out of the lab..
BSL HOME will allow your students to conduct physiology labs in the safety of their own home, dorm room, or any remote location.

Comparing Muscle Movement and Involvement between Boxing Punches In the fast-paced, high-intensity combat sport of boxing, the right punch can win a fight. However, boxing is also a sport where opponents can become exhausted in mere minutes of action, and prioritizing their strength is key to winning a fight. This team recorded EMG on test […]
