  2. Fusion beat - Wikipedia

    en.wikipedia.org/wiki/Fusion_beat

    This contrasts with the pseudofusion beat wherein the pacemaker impulse does not affect the complex of the natural beat of the heart. Pseudofusion beats are normal. Rare or isolated fusion beats caused by pacemakers are normal as well, but if they occur too frequently may reduce cardiac output and so can require adjustment of the pacemaker. [3]

  3. Premature atrial contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_atrial_contraction

    While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the atria depolarizes before the sinoatrial node and thus triggers a premature heartbeat, [1] in contrast to escape beats, in which the normal sinoatrial node fails, leaving a non-nodal pacemaker to initiate a late beat.

  4. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    Pacemaker syndrome is a condition that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation. [1] [2] It is an iatrogenic disease—an adverse effect resulting from medical treatment—that is often underdiagnosed.

  5. Ectopic pacemaker - Wikipedia

    en.wikipedia.org/wiki/Ectopic_pacemaker

    In a normal heart beat rhythm, the SA node usually suppresses the ectopic pacemaker activity due to the higher impulse rate of the SA node. However, in the instance of either a malfunctioning SA node or an ectopic focus bearing an intrinsic rate superior to SA node rate, ectopic pacemaker activity may take over the natural heart rhythm.

  6. Pacemaker - Wikipedia

    en.wikipedia.org/wiki/Pacemaker

    Percussive pacing, also known as transthoracic mechanical pacing, is the use of the closed fist, usually on the left lower edge of the sternum over the right ventricle in the vena cava, striking from a distance of 20 – 30 cm to induce a ventricular beat (the British Journal of Anaesthesia suggests this must be done to raise the ventricular pressure to 10–15 mmHg to induce electrical activity).

  7. Transcutaneous pacing - Wikipedia

    en.wikipedia.org/wiki/Transcutaneous_pacing

    During transcutaneous pacing, pads are placed on the patient's chest, either in the anterior/lateral position or the anterior/posterior position. The anterior/posterior position is preferred as it minimizes transthoracic electrical impedance by "sandwiching" the heart between the two pads [ citation needed ] .

  9. Junctional rhythm - Wikipedia

    en.wikipedia.org/wiki/Junctional_rhythm

    Junctional escape rhythm is a rhythm that still originates in the AV node or bundle of His, but beats at the intrinsic automaticity of the AV node, between 40 and 60 beats per minute. [ 10 ] Accelerated junctional rhythm
