Novel Insights into the Sinoatrial Node in Single-Cell RNA Sequencing: From Developmental Biology to Physiological Function

Journal of Cardiovascular Development and Disease, 2022
Normal cardiac automaticity is dependent on the pacemaker cells of the sinoatrial node (SAN). Insufficient cardiac pacemaking leads to the development of sick sinus syndrome (SSS). Since currently available pharmaceutical drugs and implantable pacemakers

INTERNAL CARDIAC PACEMAKERS [PDF]

American Journal of Roentgenology, 1967
There are two main pacemaker systems used in controlling the cardiac rate in Severe heart-block patients: (1) asynchronous, and (2) synchronous or P-wave actuated.These pacemakers transmit current to the electrodes by direct wire or electromagnetic communications.The main techniques of applying the myocardial electrodes to the ventricles are: (1 ...
