1 英语翻译 ECG (electrocardiogram) is a test that measures the electrical activity of the heart.The heart is a muscular organ that beats in rhythm to pump the blood through the body.The signals that make the heart's muscle fibres contract come from the sinoatrial node,which is the natural ...
Electrical Activity of the Heart Myocardial Auto rhythmic cells (1%) – These cells are smaller and contain few contractile fibers or organelles. Because they do not have organized sarcomeres, they do not contribute to the contractile force of the heart. Myocardial Contractile cells (99%) -Contra...
It was in Matteucci's rheoscopic frog in Pisa that evidence was first found for the electrical activity of the heart in 1844, and his results were confirmed and expanded 12 years later at W眉rzburg. The capillary electrometer gave a continuous record that could be photographed, and was used...

Effect of Adrenergic Activators and Inhibitors on the Electrical Activity of the Heartcardiac electrophysiologycardiac fibersarchitectureThe importance of the adrenergic system in the electrical activity of the heart can be briefly summarized by stating that the endogeneous catecholamines liberated by ...
Parts of an Electrocardiogram: The electrocardiogram, or ECG, is used by physicians to examine the electrical activity of the heart. Each ECG shows several parts of the cardiac cycle, including: P wave: atrial depolarization QRS complex: ventricular depolarization ...

In the event that the electrical activity of the heart is severely disrupted, cessation of electrical activity or fibrillation may occur. In fibrillation, the heart beats in a wild, uncontrolled manner, which prevents it from being able to pump effectively. Atrial fibrillation (see Figure 10a) is...
However, the accuracy of the reconstructed electrical heart activity is still suboptimal. This is partly due to the non-uniqueness and ill-posedness [13] of the inverse 2040 Fig. 1 Electrocardiographic imaging (ECGI) non-invasively reconstructs electrograms and activation and recovery isochrones on ...
