“…1 It is usually a benign condition that is easily managed. [2][3][4] Patients with SVT tend to be reasonably young with a mean age of less than 60 years. 1,[5][6][7] Accordingly, relatively few have known ischaemic heart disease (IHD) or other cardiac related comorbidities.…”

“…SVTs is de ned as abnormal cardiac rhythms with heart rates exceeding 100 beats/min at rest, and electropathologic substrate originating above the Bundle of His [14]. We followed that convention and chose regular SVTs including sinus tachycardia, atrial utter, atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reciprocating tachycardia (AVRT), atrial tachycardia (AT) in our study [15]. A continuous 12-lead electrocardiogram was used in patients.…”

Background: Supraventricular tachycardias (SVTs) can increase the risk of adverse events in perioperative period. Previous studies have shown that application of dexmedetomidine (DEXm) combined anesthesia during surgery can significantly reduce postoperative cardiovascular and cerebrovascular complications and mortality in patients with cardiac disease. In fact, many anesthetic drugs have cardiac protection effects. However, it is a pity that these findings are not well applied in clinical practice to treat cardiac disease. Therefore, the aim of this study was to explore the therapeutic effect of DEXm on perioperative SVTs in adult patients with non-cardiac surgery. Methods: Forty-two patients with SVTs, aged between 35 and 61 years, were randomly divided into DEXm group (group D) and midazolam group (group M). The patients undergoing elective surgery in two groups were infused intravenously DEXm 0.5-1µg/kg or midazolam 0.06-0.08mg/kg using a micro-pump for 10 minutes, respectively. The the Observer’s Assessment of Alertness/Sedation (OAA/S) score, heart rate (HR), mean arterial pressure (MAP), pulse oxygen saturation (SpO2) and occurrence of SVTs, heart rate variability (HRV) including normalized low frequency power (LFnorm), normalized high frequency power (HFnorm) and the balance ratio of sympathetic to vagal tone (LF/HF) in two groups were recorded at T0 (before the infusion DEXm or midazolam), T1 (5 minutes after the infusion), T2 (at the end of the infusion), T3 (5 minutes after the end of the infusion), and T4 (10 minutes after the end of the infusion). Results: The OAA/S score in two groups at T4 was obviously decreased compared with T0. And the OAA/S score in group M was lower than in group D at T4 (P<0.05). Compared to T0, HR and MAP in two groups were obviously decreased, and HR and MAP in group D were apparently lower than group M from T1 to T4 (P<0.05). Three patients developed mild hypotension in group D. However, none of patients developed clinically significant bradycardia, hypotension, and anoxia. There was no significant difference for SpO2 from T0 to T4 in group D. Compared to T0 or group D, SpO2 in group M obviously decreased at T2 (P<0.05). In addition, SVTs in all patients were terminated until T4 in group D after DEXm infusion. However, only two patients were finally improved in group M. Compared to T0, HFnorm were elevated, and LFnorm and LF/HF were decreased from T1 to T4, furthermore, the changes in HFnorm, LFnorm and LF/HF had statistical significance (P<0.05) in group D. However, there was no significant difference for HFnorm, LFnorm and LF/HF in group M from T0 to T4.Conclusions: Perioperative use of dexmedetomidine had a significant therapeutic effect for supraventricular tachycardias without significant adverse effects in adult patients .Trial Registration: ClinicalTrials.gov Registration Number: NCT04284150 on 26th February 2020
