Abstract

Aim: To evaluate the
electrocardiographic (ECG) parameters and hemodynamic parameters in predicting
the development of arrhythmias after free diving static apnea performance and
maximum breath hold.

Material
and Methods:
Twenty-four volunteer athletes participating in the free diving competition in
2015 (19 males (79.2%) and 5 females (20.8%)) were included in the study.
Peripheral O2 saturation (SpO2), heart rate (HR), ECG parameters (PR interval,
QRS time, T wave amplitude, corrected QT time, presence of bandle branch block
and new bandle branch block development, atrial premature beats, ventricular
premature beats) were analyzed.

Results: There was no
statistically significant difference between before static apnea measurements
(systolic blood pressure (SBP) 124.7 ± 10.8 mmHg, diastolic blood pressure
(DBP) 76.5 ± 6.7 mmHg, heart rate (HR) 80.2 ± 13.4 beats / min, SpO2 97.1 ±
0.9%) and after performance (SBP 128.8 ± 13.6 mmHg DBP 78.0 ± 5.9 mmHg, HR
85.8, ± 16.5 beats / min and SpO2 96.7 ± 2.3%)(p = 0.175; p = 0.334; p = 0.104;
p = 0.336, respectively).

Conclusion: No significant
changes were observed in ECG parameters, heart rate, saturation and blood
pressure values evaluated after static apnea performance. These findings can be
used to support that the risk of arrhythmia during static apnea does not
persist after apnea has ended.

Serbest dalış öncesi ve sonrası elektrokardiyografik değişikliklerin incelenmesi

Abstract

Amaç: Serbest dalış statik
apne performansı ile maksimum nefes tutma sonrası aritmi gelişimini öngörmede
elektrokardiyografik (EKG) parametreleri ve hemodinamik göstergeleri
değerlendirmek.

Gereç ve
Yöntemler:
Çalışmaya 2015 yılında düzenlenen serbest dalış yarışmasına katılan 24 gönüllü
sporcu dahil edilmiştir (19 erkek (%79,2) and 5 kadın (%20,8)). Performans
öncesi ve sonrası ( 5. dakikada) periferik O2 satürasyonu ( pO2), kalp hızı
(KH), EKG parametreleri ( PR aralığı, QRS süresi, T dalga amplitüdü,
düzeltilmiş QT süresi, dal bloğu varlığı ve yeni dal bloğu gelişimi, atriyal
erken atım, ventriküler erken atım varlığı) analiz edildi.

Bulgular: Sporcuların statik apne
öncesi sistolik kan basınçları (SKB) 124,7±10,8 mmHg, diyastolik kan basınçları
(DKB) 76,5±6,7 mmHg, kalp hızı 80,2 ±13,4 atım/dk, pO2 %97,1±0,9 ve performans
sonrası SKB 128,8±13,6 mmHg, DKB 78,0 ±5,9 mmHg, KH 85,8±16,5 atım/dk, pO2
%96,7±2,3 arasında istatistiksel olarak anlamlı fark saptanmadı ( sırasıyla
p=0,175; p=0,334; p=0,104; p=0,336).

Sonuç: Statik apne
performansı sonrası değerlendirilen EKG parametrelerinde, kalp hızında,
satürasyon ve tansiyon değerlerinde herhangi bir anlamlı değişiklik izlenmedi.
Bu bulgular statik apne esnasında gelişebilecek aritmi riskinin apne
sonlandıktan sonra devam etmediğini desteklemede kullanılabilir.
