Heart The heart acts as a pump and maintains circulation of the blood by alternate concentration and relaxation of cardiac muscle (the myocardium). It generally contracts at
The heart is made up of many cardiomyocytes, or cardiac muscle cells, that contract in response to electrical stimulation to produce the heart beat. It is vitally important for the cardiomyocytes to coordinate their contractions, so tha...
Aims Animal studies revealed that the hyperpolarization-activated pacemaker current, I<sub>f</sub>, contributes to action potential (AP) generation in sinoatrial node (SAN) and significantly determines heart rate. I<sub>f</sub> is becoming a novel therapy target to modulate heart rate. Yet, no...
Main Regularities of Mutual Location of Different Pacemaker Cells in the Rat Heart Sinoatrial Node It was shown that the dominant pacemaker region and the functional tail are located in the lateral area of the central part of the sinoatrial node, ... PV Sutyagin,AG Kamkin,OY Gurina - 《Bulle...
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 pacemaker of...
Heart rate is regulated by the autonomic nervous system but little is known about the pattern of innervation of the pacemaker in the sinoatrial node, or the subpopulations of nerves involved. Therefore in this study the pacemaker was located using electrophysiological methods and the pattern of ...

During the pathological bradycardia incessant runs of irregular tachycardia from the region of atrial extension of AV node were observed. The bradycardia runs were due to advanced functional AV nodal block. The patient was qualified for pacemaker implantation and antiarrhythmic treatment by his GP. ...
Conclusions: TTE is very safe, easy, feasible and economical in guiding atrioventricular node ablation and VVI pacemaker implantation. 展开 关键词: Echocardiography X-ray fluoroscopy Atrial fibrillation Atrial flutter Catheter ablation radiofrequency current ...
