Artificial Pacing of the Heart Using Transvenously Applied Endocardial Electrodes: A Case Presentation and Method Discussion

Year 1970, Volume: 23 Issue: 2, 497 - 504, 30.06.1970

Abstract

This clinical report discusses a case of idiopathic hypertrophic subaortic stenosis (IHSS) in an 18-year-old male who exhibited electrocardiographic findings mimicking anterior myocardial infarction. The patient presented with exertional headaches, dizziness, and occasional syncope. Clinical and hemodynamic studies, including apexcardiogram, phonocardiogram, vectorcardiogram, and left heart catheterization, revealed hallmark signs of IHSS—subvalvular gradient, systolic pressure drop across the outflow tract, and post-extrasystolic potentiation. Coronary angiography was normal, ruling out ischemic disease. The study emphasizes the diagnostic challenge in distinguishing IHSS from actual myocardial infarction based on ECG alone, especially in young individuals with normal coronaries.

Miyokard İnfraktüsü EKG Örneği Gösteren Bir İdiyopatik Hipertrofik Subaortik Stenoz (IHSS) Vak’ası

Year 1970, Volume: 23 Issue: 2, 497 - 504, 30.06.1970

Abstract

Bu klinik raporda 18 yaşındaki erkek bir vakada saptanan idiyopatik hipertrofik subaortik stenoz (IHSS) ve bu hastalığın miyokard infarktüsünü taklit eden EKG bulguları ele alınmaktadır. Hasta, eforla tetiklenen baş ağrısı, baş dönmesi ve senkop atakları ile başvurmuştur. Yapılan fizik muayene, apekskardiogram, fonokardiyogram, vektörkardiogram ve sol kalp kateterizasyonu sonucunda IHSS’e özgü bulgular saptanmıştır: sol ventrikül ejeksiyon yolu üzerinde sistolik basınç farkı, ekstrasistol sonrası intraventriküler basınç artışı ve karakteristik morfolojide karotid dalga formu. Koroner arterlerde patoloji saptanmamıştır. EKG'deki anterior infarktüs örneği, lokalize septal hipertrofiye veya nadir fibrotik değişikliklere bağlanmıştır. Çalışma, genç vakalarda gerçek miyokard infarktüsünden ayırıcı tanının önemini vurgulamaktadır.
