The atrial pacing mode is preferably the AVT pacing mode, wherein the atria (A) are paced, the ventricles (V) are sensed, and the atrial pacing is triggered (T) by the ventricular sense signals. Alternatively, the ADD pacing mode can be employed if the underlying sinus atrial ...
Blanking period activated after Vs is equal to 100 m s and after Ap is equal to 30 m s. Ap: Atrial Pacing; Vs: Ventricular Sensing. 2. Discussion Several clinical studies [[1], [2], [3], [4], [5], [6]] have shown in the past that unnecessary ventricular pacing can be ...
Cardiac output is increased in proportion to heart rate, and atrial pacing has been shown to reduce the incidence of atrial fibrillation in some patients. These considerations were combined and produced the hypothesis that dual-chamber pacemakers would permit optimal drug therapy and improved ...
METHODS: Fifty nine NYHA class III patients with left ventricular systolic dysfunction, chronic atrial fibrillation, slow ventricular rate necessitating permanent ventricular pacing, and a wide QRS complex (paced width >or=200 ms), were implanted with transvenous biventricular-VVIR pacemakers. This ...

Below: Rhythm strip lead II with atrial pacing (Ap), LV stimulus artefact and RV stimulus artefact, 60 milliseconds later. There is a latency period between the atrial stimulus artefact and the paced P wave (red highlight). Sign in to download hi-res image Figure 6. Electrocardiograph (ECG...
Objectives We aimed to compare the hemodynamic effects of right-atrial-paced (DDD) and right-atrial-sensed (VDD) biventricular paced rhythm on cardiac resy... Alain,Bernheim,and,... - 《Journal of the American College of Cardiology》 被引量: 163发表: 2005年 Ventricular endocardial right bif...
and an ECG acquired within 30 days of the CMR examination. Exclusion criteria were ECG confounders such as atrial fibrillation or flutter, abundant premature ventricular contractions (bigeminy/trigeminy), paced rhythm, hypertrophic cardiomyopathy, congenital heart disease, Takotsubo cardiomyopathy, amyloidosis...
ATP = antitachycardia pacing; ICD = implantable cardioverter-defibrillator; RV = right ventricle; RVOT = right ventricular outflow tract; VF = ventricular fibrillation; VP = Ventricular Paced; VS = Ventricular Sensed; VT = ventricular tachycardia. Underlying etiology of cardiomyopathy was ischemic ...
considered to have a potential prognostic impact, were included: age, sex, arterial hypertension, diabetes mellitus, dyslipidemia, coronary artery disease, previous myocardial infarction, atrial fibrillation, estimated glomerular filtration rate, NYHA functional class II to IV, LVEF, left atrial volume in...
