ECG tutorial: Pacemakers - UpToDate
Dec 19, 2023 · Atrial and ventricular pacing can be seen on the electrocardiogram (ECG) as a pacing stimulus (spike) followed by a P wave or QRS complex, respectively. The ECG has the ability to show normal and abnormal pacemaker function.
The role of pacemakers in the prevention of atrial fibrillation
Jun 14, 2022 · Many patients with atrial fibrillation (AF) have sinus node dysfunction with symptomatic bradycardia requiring pacemaker placement. Moreover, antiarrhythmic drug treatment may lead to sinus or atrioventricular nodal dysfunction that may require pacing in order to permit up-titration of drug dose.
Modes of cardiac pacing: Nomenclature and selection - UpToDate
Aug 7, 2023 · (See "Permanent cardiac pacing: Overview of devices and indications".) To facilitate the use and understanding of pacemakers, a standardized classification code has been developed. Most patients can be managed with one of three common modes (AAI, VVI, or DDD), with or without rate responsiveness.
Cardiac resynchronization therapy and conduction system pacing …
Sep 26, 2023 · Cardiac physiologic pacing (CPP) is defined here as any form of cardiac pacing intended to restore or preserve synchrony of ventricular contraction and includes both conventional cardiac resynchronization therapy (CRT) and the more recently adopted conduction system pacing (CSP).
Temporary cardiac pacing - UpToDate
Any symptomatic indication for permanent cardiac pacing is potentially an indication for temporary cardiac pacing. However, temporary cardiac pacing is most commonly used for patients with symptomatic bradyarrhythmias, most frequently due to atrioventricular (AV) nodal block.
Atrial fibrillation: Atrioventricular node ablation - UpToDate
Jan 9, 2023 · In patients with atrial fibrillation (AF), the ventricular rate is determined in large part by the conduction properties of the atrioventricular (AV) node. In the typical patient with untreated AF, the ventricular rate can reach 150 beats per minute or higher.
Permanent cardiac pacing: Overview of devices and indications
Jun 27, 2023 · By providing an appropriate heart rate and heart rate response, cardiac pacing can reestablish effective circulation and normalize hemodynamics that are compromised by a slow heart rate. This topic will present a broad review of the role of cardiac pacing in a …
UpToDate
Atrial and ventricular pacing can be seen on the electrocardiogram (ECG) as a pacing stimulus (spike) followed by a P wave or QRS complex, respectively. The ECG has the ability to show normal and abnormal pacemaker function.
Overview of atrial flutter - UpToDate
Atrial flutter is an abnormal cardiac rhythm characterized by rapid, regular atrial depolarizations at a characteristic rate of approximately 300 beats/min and a regular ventricular rate of about 150 beats/min in patients not taking atrioventricular (AV) nodal blockers.
Perioperative management of patients with a pacemaker or
Sep 11, 2024 · The ECG is examined to determine if the patient has atrial and/or ventricular pacing spikes. Pacing dependence is assumed if all beats are paced. In the absence of identifiable pacing artifacts, a consistently regular rhythm at a rate of 60, 65, or 70 beats/minute (bpm) usually indicates pacing.
