Abstract

This study was designed to assess the relationship between the early recurrence of atrial tachyarrhythmia (ERAT) and the pattern of the immediate atrialactivities following electrical cardioversion (DC/CVN). We tested thehypothesis that the early atrial activity pattern and time predicted ERAT. We investigated clinical and electrocardiographic variables to predict ERAT in20 minutes in randomly selected 123 procedures in 123 patients.Electrocardiograms recorded continuously were assessed for PP intervals andthe type of atrial activity (sinus, atrial premature, fusion or junctional)for, at most, the first 35 beats following successful electrical cardioversion. No-ERAT group consisted of 101 procedures in 101 patients (mean age 66±13 years) without early recurrence of atrial tachyarrhythmia, whereas ERAT group (n= 22)(mean age 69±11 years) had recurrence within 20 minutes following successfulDC/CVN. There was no difference between groups regarding drugs received, including antiarrhythmics. Atrial tachyarrhythmia in the ERAT group recurred in 118±280 seconds (3 sec-20 min). History of hypertension was significantly higher the in ERAT group. Increased pPP50 %, increased PAC/total beat ratio, and minimum PP interval have been found as predictors of ERAT in this study.We concluded that history of hypertension was the only clinical harbinger ofERAT in 20 minutes following successful DC/CVN. Frequent premature atrialactivity with shorter coupling interval analyzed from surface ECG may identifya subgroup of patients who may benefit from immediate intervention to preventfrom ERAT. Suppression of premature atrial activity during CVN may be a goodtarget in preventing ERAT in this group of patients.

Özet

Giriş: Bu çalışma atriyal takiaritmilerin erken nüksü (ATEN) ile elektrikikardiyoversiyondan (DC/CVN) hemen sonraki atriyal aktivasyon arasındakiilişkiyi değerlendirmek amacıyla düzenlendi. Erken atriyal aktivasyon paterniile zamanının ATEN`nü öngöreceği hipotezi test edildi. Metodlar: Çalışmada tesadüfi seçilmiş 123 hastada yapılan 123 DC/CVN işleminden sonra ilk 20 dakika içinde ATEN`nün öngörülmesinde klinik veelektrokardiyografik değişkenleri inceledik. Başarılı elektriki kardiyoversiyon süresince devamlı alınan EKG kayıtları üzerinden en az 35 atriyal atım olmaküzere atriyal aktivite tipi (sinus, atriyal erken vuru, füzyon veya kavşakatımı) ve PP aralıkları değerlendirildi. Sonuçlar: ATEN izlenmeyen 101 hasta (ortalama yaş 66±13 yıl) nükssüz grubu’nuoluştururken, nüks grubu’nda ise (n=22) (ortalama yaş 69±11 yıl) başarılıDC/CVN sonrası 20 dakika içinde ATEN izlendi. Nüks grubunda atriyal aritmi118±280 sn içinde (3 sn-20 dakika) nüks etti. Kullanılan antiaritmikler vediğer ilaçlar yönünden gruplar arasında fark yoktu. Nüks grubunda hipertansiyon sıklığı anlamlı olarak fazlaydı. Çalışmada yüksek pPP50 % değeri, artmışPAC/total atım oranı ve minimum PP intervali ATEN’nü öngörmekteydi. Sonuç: Hipertansiyon hikayesi DC/CVN sonrası ilk 20 dakika içinde ATEN’inöngörülmesinde tek klinik belirleyici olarak saptandı. Yüzey EKG’sinden ölçülen“coupling” aralığı kısa sık erken atriyal aktivitenin varlığı, ATEN’ünönlenmesinde hızlı müdahaleden fayda görecek bir grubu ortaya çıkarabilir. Bugrup hastalarda ATEN’ün önlenmesinde CVN esnasında erken atriyal aktiviteninbaskılanması hedef alınabilir.
