pacemakerA presumed abnormal electrocardiogram (ECG) was obtained from an asymptomatic patient with a pacemaker. Systematic evaluation of the ECG revealed that the artifact was due to a physiological sensor in the pacemaker which was displayed when the enhanced pacemaker detection features on the ECG ...
pacemaker (MC 6–8), supraventricular tachycardia (MC 8–4-2) and major QT prolongation index (QT index ≥116%) [16]. In order to ensure the quality of coding, the ECG tests classified as displaying major alterations were then manually reviewed by two cardiologists. ...
Average ECG resolution of acute pericarditis has to be differentiated from a normal variant cccurring in some normal young persons that is often referred to incorrectly as early repolarization. The latter consists, in the left chest leads, of normal ST-segment elevation associated with usually ...

Explain the term 'pacemaker of the heart.' What is an ECG or an EKG? Which of the following options is correct? The T wave of the ECG represents A. ventricular relaxation. B. ventricular contraction. C. atrial relaxation. D. atrial contraction. E. firing of ...
Correlation of the vector magnetocardiogram with the vector electrocardiogram in normal subjects and in anterior and inferior myocardial infarction The relationship between the unipositional vector magnetocardiogram (VMCG) and the Frank vector electrocardiogram (VECG) was studied with a stepwise multip......
An implantable synchronous pacemaker for the long term correction of complete heart block The performance of the pacemaker during normal sinus rhythm and atrial arrhythmias has been discussed and illustrated with electrocardiograms. After implantation ... DA Nathan,S Center,CY Wu,... - 《American Jou...
A variety of nonsinus rhythms with normal heart rates may be encountered clinically and are important to recognize. These rhythms may present with narrow or wide QRS complexes on the 12﹍ead electrocardiogram (ECG). Ectopic atrial rhythms may result from failure of the sinus node and the ...
The pacemaker was subsequently removed at 4 years of age after resumption of normal sinus rhythm, however, he has retained epicardial leads.
