“…A ventricular rate less than 100 bpm is very rare in AVNRT [7,9]. Previous studies associated a slow rate AVNRT with advanced age, higher Wenckebach cycle length, AV node antegrade effective refractory period values and higher atrial vulnerability [10][11][12][13]. In our patient this could be associated with his AV conduction abnormalities, the previous RFCA procedure and the beta-blocking and Amiodarone treatment [14].…”

Introduction: Atrioventricular nodal reentrant tachycardia (AVNRT) is the most frequent supraventricular tachycardia, commonly manifesting as autolimited paroxysmal episodes of rapid regular palpitations that exceed 150 beats per minute (bpm), dizziness and pounding neck sensation. Case presentation: We present a case of a male patient, 70 years old, with ischemic heart disease and slow-fast AVNRT treated with radiofrequency catheter ablation (RFCA) in March 2019, with regular 6-months follow-ups. He was readmitted in our department in November 2020 for rest dyspnea and incessant fluttering sensation in the neck, without palpitations. The event electrocardiogram (ECG) was initially interpreted by general cardiologist as accelerated junctional rhythm, 75 bpm. Due to the persistence of symptoms and ECG findings, a differential diagnosis between reentry and focal automaticity was imposed. The response to vagal maneuvers and Holter ECG monitoring characteristics provided valuable information. We suspected recurrent slow ventricular rate typical AVNRT, which was confirmed by electrophysiological study and we successfully performed the RFCA of the slow intranodal pathway. Conclusion: AV nodal reentry tachycardia may have an unusual presentation, occurring in elder male patients with structural heart disease. Antiarrhythmic drugs can promote reentry in this kind of patients. In cases of slow ventricular rate, vagal maneuvers and Holter ECG monitoring can help with the differential diagnosis. The arrhythmia can be successfully treated with RFCA with special caution regarding the risk of AV block.

“…Atrioventricular nodal reentrant tachycardia (AVNRT) is a common type of supraventricular arrhythmia and mostly affects older women and men (1,2) . AVNRT occurs because of a reentrant circuit located in or near the atrioventricular (AV) node causing the heart to beat prematurely (3) .…”

Introduction:Heart rate variability (HRV) is associated with sympathetic tone. Studies have disputed the interpretation of the low frequency (LF) and low/high frequency (LF/HF) ratio for the indication of sympathetic cardiac control and autonomic balance. This study aims to investigate the association between HRV parameters and atrioventricular nodal reentrant tachycardia (AVNRT) and observe the effect of autonomic nervous system on AVNRT. Patients and Methods:In total, 354 subjects with palpitations underwent the electrophysiological study (EPS). Most (71%; 253/354) patients had at least an ambulatory Holter ECG recording of 24 h. As a consequence of the exclusion criteria, 160 individuals were classified into two groups: control group (no arrhythmia induced, n= 90) and AVNRT group (n= 70).Results: Daytime and nighttime LF and LF/HF ratio were significantly higher in the AVNRT group (p< 0.05) than in the control group. Interestingly, daytime ultra-LF, very LF, and total power were significantly lower in the AVNRT group.Conclusion: AVNRT is associated with altered sympathovagal balance. Furthermore, increased LF and LF/ HF may be indicative of enhanced sympathetic activity in patients with AVNRT because of inhomogeneous ventricular activation via the slow accessory pathway.Giriş: Kalp hızı değişkenliği (HRV) sempatik ton ile ilişkilidir. Çalışmalar sempatik kardiyak kontrol ve otonom denge endikasyonu için düşük frekans (LF) ve düşük/yüksek frekans (LF/HF) oranının yorumlamasını tartışmışlardır. Bu çalışma, HRV parametreleri ile atriyoventriküler nodal reentrant taşikardi (AVNRT) arasındaki ilişkiyi araştırmayı ve otonomik sinir sisteminin AVNRT üzerindeki etkisini gözlemeyi amaçlamaktadır. Hastalar ve Yöntem:Çarpıntısı olan 354 olguya elektrofizyolojik çalışma yapıldı (EPS). Hastaların %71 (253/354)'i en az bir 24 saatlik ambulatuvar Holter elektrokardiyografi (EKG) kaydına sahipti. Dışlama kriterlerinin bir sonucu olarak, 160 birey iki gruba ayrıldı; kontrol grubu (aritmi indüklenmedi, n= 90) ve AVNRT grubu (n= 70).Bulgular: Gündüz ve gece LF ve LF/HF oranı AVNRT'de kontrollerden anlamlı derecede yüksekti (p< 0.05). İlginç olarak, gündüz ultra düşük frekans, çok düşük frekans ve toplam güç AVNRT'de anlamlı olarak düşüktü.Sonuç: AVNRT değişmiş sempatovagal denge ile ilişkilidir. Dahası, artmış LF ve LF/HF, AVNRT hastalarında yavaş aksesuar yolla homojen olmayan ventriküler aktivasyonun bir sonucu olarak artmış sempatik aktivitenin bir göstergesi olabilir.Anahtar Kelimeler: Atriyoventriküler nodal reentrant taşikardi; kalp hızı değişkenliği; düşük frekans; düşük/yüksek frekans Lütfü Aşkın

Clinical and electrophysiological characteristics of the patients with relatively slow atrioventricular nodal reentrant tachycardia

Abstract: Our experience demonstrates that clinical and electrophysiologic characteristics of AVNRT patients with relatively slower tachycardia rates were quite different compared to the faster AVNRT cases.
