ECG Pacemaker malfunction, troubleshooting and ECG Conventional surface ECG can reveal the following types of pacemaker dysfunction: Failure to capture (FTC) , which means that the…

…that drive the cells to threshold. Any stimulus driving the membrane potential to threshold will evoke an action potential, which will subsequently propagate to neighboring…

…e currents generated by tissues that the electrode is not connected to). Also, external signals from electronics (cell phones, computers, etc) must also be ignored…

…In PET (Positron Emission Tomography), radiotracers emit positrons. When a positron collides with an electron, they annihilate each other, producing two gamma photons emitted in…

…compare electrical currents in two measurement points. The electrophysiological basis of the ECG leads The movement of charged particles generates an electric current. In electrocardiology…

…Piezoelectric crystals have unique electromechanical properties. When an electric current is applied to a piezoelectric crystal, it starts to vibrate and these vibrations generate sound…
