AI Article Synopsis
- HIV patients are at increased risk for heart issues, and the quality of ECG readings from handheld devices deteriorates as the disease progresses.
- A study involving 263 Kenyan adults analyzed the readability of 30-second ECG recordings made during routine check-ups, with 76.4% readable and 23.6% unreadable results.
- The findings suggest that as the HIV infection stage advances, patients are more likely to have unreadable ECGs, indicating that mobile devices may not accurately diagnose heart arrhythmias in these individuals.
Article Abstract
Introduction: HIV patients are at higher risk for cardiovascular disease and cardiac arrhythmias which can be recorded by a handheld single‑lead ECG device. Quality of ECG depends on the skin condition, which worsens with the progression of HIV infection.
Objective: To study the quality of the ECG signal acquired by a mobile ECG device in patients with different clinical stages of human immunodeficiency virus (HIV) infection.
Patients And Methods: We studied the quality of 30-second single lead ECGs obtained by a handheld ECG device (Kardia; AliveCor Inc., San Francisco, USA) in 263 Kenyan adults (203 women) in various stages of HIV. The recordings were made during routine check-ups at the outpatient clinics. ECG quality was categorized as readable (not interfering with clinical interpretation) or unreadable (impossible clinical interpretation). The progression of the HIV infection was estimated using the World Health Organization AIDS Clinical Staging (WACS) scale, ranging from stage 1 (asymptomatic generalized lymphadenopathy) to stage 4 (wasting syndrome and Kaposi sarcoma).
Results: The median age of patients was 46 (39-53) years. ECG was readable in 201 patients (76.4%) and unreadable in 62 (23.6%). The WACS score > 1 was associated with 3.95 odds ratio (95% confidence interval 2.14-7.29; p < 0.0001) for the acquiring an unreadable ECG (univariate logistic regression adjusted to age, sex, body mass index and time since HIV).
Conclusions: ECG quality recorded by a touch ECG device worsens with advancing HIV infection. For this reason, the accuracy of arrhythmia diagnosis by mobile ECG appears to be limited in HIV patients.

Diagnostic Accuracy of Apple Watch Electrocardiogram for Atrial Fibrillation: A Systematic Review and Meta-Analysis.
JACC Adv
February 2025
Department of Cardiology, Oklahoma Heart Hospital, Oklahoma, USA.
Background: Electrocardiography (ECG) is the gold standard for the diagnosis of atrial fibrillation (AF). Recently, smartwatches like the Apple Watch have emerged as a promising, user-friendly device for rapid detection and diagnosis of AF, but the reliability and diagnostic accuracy still remain controversial.
Objectives: The purpose of this study was to perform a systematic review and diagnostic test accuracy meta-analysis evaluating the diagnostic performance of the Apple Watch ECG in detecting AF.

Cardiac arrhythmias are major global health concern and their early detection is critical for diagnosis. This study comprehensively evaluates the effectiveness of CNNs and LSTMs for the classification of cardiac arrhythmias, considering three PhysioNet datasets. ECG records are segmented to accommodate around ∼10s of ECG data.

Study Objectives: Evaluate the performance of the SANSA device to simultaneously assess obstructive sleep apnea (OSA) and cardiac arrhythmias.
Methods: Participants suspected or known to have OSA underwent polysomnography (PSG) while wearing SANSA. SANSA's algorithm was trained using 86 records and tested on 67 to evaluate training bias.
Beaware of Intracardiac Potentials Induced by Intravascular Lithotripsy.
Catheter Cardiovasc Interv
January 2025
Department of Cardiology, Ageo Central General Hospital, Saitama, Japan.
Background: Intravascular lithotripsy (IVL), that generates shockwaves through spark gap discharge between emitters, has been increasingly used to treat severely calcified coronary artery lesions. However, there is a question as to whether IVL has no electrical effects on endocardial tissues or cardiac implantable devices (CIEDs).
Aims: The aim of this study was to investigate the effects of IVL-induced intracardiac potentials on cardiac electrophysiology and CIEDs.

A young man in his 30s presented to us with multiple episodes of syncope and exertional dyspnoea for the last 2 weeks. He was diagnosed with squamous cell carcinoma of the lower one-third of the oesophagus in 2021 for which he was treated with neoadjuvant chemoradiotherapy, followed by McKeown oesophagectomy. At 2-year follow-up, he had developed a soft tissue swelling in the scalp, which was diagnosed as a tumour recurrence and radiotherapy was initiated.
