心房室期外收縮的心臟病徵狀和治療方式-心臟血管專科

請問心房室期外收縮是什麼？嚴重嗎？？

醫生您好，跟你請教一下我的24小時心電圖檢查報告看起來是有心房室期外收縮，我的狀況嚴重嗎？
需要治療嗎？
附上我的24小時心電圖、心臟超音波及運動心電圖等報告，請醫生看一下，綜合評估診斷一下我是什麼心臟疾病，如何治療，謝謝。
1.24小時心電圖：Holter Report: Clinical diagnosis: Syncope Test date : 2022/05/19 Analysis date: 2022/05/20 Hoopup time : 10:53 Analysis Time: 23 hr 01 minAnalysis result: Technical quality of record: Good Dominant rhythm: Sinus Total Beats: 105484 Min HR : 53 BPM at 02:25:03 Avg HR : 76 BPM Max HR : 122 BPM at 08:29:25 Heart Rate Variability ASDNN 5 : 44.2 msec SDANN 5 : 126.5 msec SDNN : 132.7 msec PVCs/couplets/VT: 1903/0/0 (Longest 0 beats at _:_:_) PACs/couplets/AT: 7/1/0 (Longest 0 beats at _:_:_) Fastest : 0 BPM at _:_:_ Drop/Late : 0/0 Longest N-N : 1.4 sec at 03:32:17 Others: _Comments: 1. Sinus rhythm with a rate ranging 53-122 bpm and a mean of 76 bpm. 2. Few isolated PACs 3. Several isolated PVCs (1903, 1.8%) 4. No AV block 5. No significant long pause 6. Heart rate variability intact.2.心臟超音波：Report: 【Atrium and Aortic Root】 AO (mm) = 31 LA (mm) = 33 【Left Ventricle】 IVS (mm) = 9 PW (mm) = 9 EDD (mm) = 43 ESD (mm) = 29 LVEF： by M-mode measurement：60 % 【Valve】 MS: nil; MR: Mild; AS: nil; AR: nil; TS: nil; TR: trivial; PS: nil; PR: Mild; Conclusion: Rhythm and Appearance: . Sinus rhythm Left ventricle: . Systolic function: Normal . Wall motion: Normal . Diastolic function: Normal Right ventricle: . Systolic function: Normal Valves: . Mild mitral, pulmonary regurgitation.3.運動心電圖：Treadmill Exercise Test Report: Protocol: Standard Bruce BH: 166 cm; BW: 65 kg Study Date:2022/05/20 Test type: Stress ECG Provisional Diagnosis: chest tightness Medication within 2 weeks: no Chest pain: nil Arrhythmia: no;History of syncope: no Evidence of previous MI: no Risk of coronary events: nil Life style: sedentaryEnd points: target heart rate acheivedResults: The patient exercised according to the Bruce for 09:40, achieving a work level of Max. METs: 12.3. Resting heart rate initially 73 bpm, rose to a max. heart rate of 162 bpm which represents 91 % of the maximal age-predicted heart rate. Resting blood pressure 115/71 mmHg, rose to a maximum blood pressure of 141/80 mmHg. The exercise test was stopped due to target heart rate acheivedInterpretation: 1. Resting ECG: incomplete RBBB 2. Stress: RPP(*100) _; Chest pain: Nil ST segment: DTS____, Max ST/HR slope:____ at lead ___ Horizontal/downsloping ST depression: Nil Upsloping ST depression: ＜1.5mm 3.Probably negative for myocardial ischemia 4. No major arrhythmia induced 5.others: Isolated PVCs during stage 1, 3 and 4.
