Cardiovascular

Transvenous Cardiac Pacing: 12-year Experience in Lagos, Nigeria.

TL;DR

A 12-year, three-centre retrospective review in Lagos, Nigeria of 133 patients who had permanent pacemaker insertion for symptomatic bradycardia found that complete heart block was the main indication, nearly all devices were single-chamber VVIR, and acute lead dislodgement was the most frequent complication; the authors conclude that PPI has revolutionised treatment of symptomatic bradycardia and that upgrading and affordability would benefit more patients.

Key Findings

133 patients underwent permanent pacemaker insertion for symptomatic bradycardia at three Lagos hospitals over 12 years, with equal gender distribution.

  • Retrospective review of records from January 2011 to December 2022 in three centres.
  • 68 males and 67 females.
  • Data were analysed using SPSS version 24.

Patients receiving pacemakers were mostly elderly, with a wide age range.

  • Age range was 26-99 years.
  • Median age was 70 years; mean age was 67.72 ± 13.97 years.

Patients presented with markedly slow pulse rates.

  • Mean pulse rate at presentation was 38.70 ± 6.56 per minute.

Complete heart block was the most frequent indication for pacemaker insertion.

  • 117 of 133 patients (88%) had complete heart block as the indication.

Single-chamber VVIR pacemakers were used in almost all patients.

  • Single-chamber pacemaker (VVIR) was inserted in 95.5% of patients.

Acute lead dislodgement was the most frequent complication.

  • Reported in the abstract as the most frequent complication; no frequency is given in the abstract.

The authors conclude pacemaker insertion has revolutionised treatment of symptomatic bradycardia and advocate upgrading standards and improving affordability.

  • They state that PPI contributes to increased life expectancy.
  • They state that upgrading and increased affordability would benefit more patients with indications for PPI.
  • The study aim was to review outcomes locally, increase awareness, and advocate for an upgrade of the current standard.

What This Means

This study looked back at the records of 133 people in Lagos, Nigeria, who had a permanent pacemaker fitted between 2011 and 2022 at three hospitals. Most were older adults (average age about 68) with a very slow heart rate, averaging about 39 beats per minute when they arrived. The main reason for a pacemaker was complete heart block, a condition in which electrical signals between the upper and lower chambers of the heart are blocked, which affected 88% of patients. Almost all patients (95.5%) received a simple single-chamber pacemaker rather than more advanced types. The most common complication was a pacing wire moving out of position soon after insertion. The authors suggest that pacemakers have greatly improved care for slow heart rhythms and may extend life. The researchers argue that better access, upgraded equipment and lower costs could help more patients who need pacemakers in Nigeria. This was a record review without a comparison group, so it describes local practice rather than testing which approach works best.
