Abstract

Insights

The prevalence of cardiac pacemaker exteriorization is 2.6%, with no identified risk factors in this population. Surgical technique may be a key factor, warranting further investigation into implantation methods.

Area of Science:

  • Cardiology
  • Medical Device Technology
  • Infectious Disease Prevention

Background:

  • Infection is a primary complication following permanent pacemaker implantation.
  • Pacemaker exteriorization presents a significant clinical challenge.
  • Understanding its prevalence and risk factors is crucial for patient care.

Purpose of the Study:

  • To determine the prevalence of cardiac pacemaker exteriorization.
  • To identify and analyze the frequency of risk factors associated with this complication.
  • To investigate these factors within a specific tertiary care center.

Main Methods:

  • A descriptive, cross-sectional study design was employed.
  • Data collected from September 2005 to September 2010.
  • Case-control analysis matched by age, sex, and diabetes status; statistical analysis included chi-squared and Fisher exact tests.

Main Results:

  • A total of 3192 permanent pacemakers were implanted.
  • 83 cases of pacemaker exteriorization were identified.
  • The overall prevalence of exteriorization was 2.6%, with a mean age of 71 years in affected patients.

Conclusions:

  • The study found a 2.6% prevalence of cardiac pacemaker exteriorization, consistent with prior research.
  • No previously described risk factors were identified as causative in this patient cohort.
  • Surgical technique emerged as a potential significant risk factor, necessitating further research into various implantation methods.

Mechanism of Cardiac Arrhythmias01:28

Mechanism of Cardiac Arrhythmias

Arrhythmias are irregular heart rhythms occurring when the heart's electrical impulses become abnormal. These disturbances can lead to various symptoms, depending on their severity and the underlying cause. Some common factors contributing to arrhythmias include hypoxia, ischemia, electrolyte imbalances, excessive catecholamine exposure, drug toxicity, and muscle overstretching. Arrhythmias can be classified into two main types based on the rate and site of origin of abnormal heart rhythms.

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Decreased pulse rate01:14

Decreased pulse rate

Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Pericarditis I: Introduction01:22

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...
