A comparison of the chronotropic and dromotropic actions between adenosine triphosphate and edrophonium in patients undergoing coronary artery bypass graft... Objective: To compare the effects of the stimulation of adenosine receptors and acetylcholine receptors in the cardiac conduction system in patients...
Adhesive electrodes are affixed to the skin surface allowing measurement of cardiac impulses from many angles. The ECG provides 3-dimensional information about the conduction system of the heart, the myocardium , and other cardiac structures. In the healthy state, an ECG records predictable, ...

They also allow small molecules and ions to pass between neighboring cardiac muscle cells, enabling nutrient exchange and swift conduction of action potentials between each cell membrane.What are Intercalated Discs? The human heart is an amazing organ. It beats an average of 60 - 100 per minute ...
Quantitative PCR was performed on a StepOnePlus Real Time PCR system (Life Technologies). Quantitative PCR parameters for cycling were as follows: 50°C incubation for 2 min, 95 °C for 10 min, 40 cycles of PCR at 95 °C for 15 s, and 60 °C for 1 min. All reactions were ...
The 54 patients considered from the database for the present study were those with a QRS duration <120 ms (on a control standard ECG recorded prior to the procedure) and without previous myocardial infarction, indicated by the ECG QRS scoring system of Selvester et al. (13) and its myocardi...
