Dysrhythmias IV: Characteristics of Bradyarrhythmias

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
Pre-Procedural Preparation

Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Mitral Regurgitation I: Introduction

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Background:

Chronic right ventricular (RV) pacing causes dyssynchrony, increasing risks of heart failure and atrial arrhythmias.
His bundle pacing (HBP) is physiological but has limitations like lead stability and a steep learning curve.
Left bundle branch pacing (LBBP) emerges as a novel technique to overcome HBP limitations.

Purpose of the Study:

To review the criteria and methodology for successful left bundle branch pacing (LBBP).
To highlight LBBP as a potential alternative to conventional pacing methods.
To discuss the safety and efficacy of LBBP in cardiac conduction system disease.

Main Methods:

Review of literature on left bundle branch pacing (LBBP) techniques.
Detailed discussion of criteria for left bundle branch (LBB) capture.
Description of pacing hardware, including Medtronic SelectSecure®3830 lead and C315His®/C304His® sheaths.

Main Results:

LBBP demonstrates feasibility, safety, and efficacy, offering low pacing thresholds.
Left bundle potential is typically demonstrable, except in specific heart block or bundle branch block scenarios.
LBBP shows promise in patients with left ventricular dysfunction and conduction abnormalities.

Conclusions:

LBBP is a safe and effective technique for pacing the cardiac conduction system.
It presents a viable alternative to His bundle pacing and biventricular pacing.
Further randomized trials are needed to confirm long-term safety and clinical outcomes compared to traditional pacing.
