這兩天這裏圍繞著豆豆RV的十邁心率有不少討論。有人羨慕她強大的心髒，有人懷疑她速度過快。無獨有偶，昨天在跑群聊天群裏，一位女跑友也提到心率問題。這是她昨天跑tempo的心率：
她是一個很強的馬拉鬆跑者，但是這幾年總發現自己的跑步心率降不下來，很難降到150以下。昨天最後衝刺時高達212.
豆豆RV前天的十邁tempo平均心率有160，也是降不下來。但是最高心率是173。不知道她的最高心率能達到多高。不是給你帶來恐慌，是想提醒你一下注意有沒有其他症狀。listen to your body.
針對我這位跑友，有為年長的跑友建議去做一下EKG排除問題，他提出了exercise induced SVT。也提醒這裏的跑友們注意一下。
這裏是網上信息：
Exercise-induced supraventricular tachycardia (SVT) is a rapid heart rate that begins and ends suddenly, often during or after intense exercise. It's characterized by a fast heart rate (over 150 beats per minute) with a narrow QRS complex. While often harmless, it can be a trigger for other heart conditions or may indicate an underlying issue.
Elaboration:
-
SVT is a type of tachycardia, a fast heart rate, where the rapid heartbeat originates above the ventricles of the heart (hence "supraventricular").
-
Exercise can trigger SVT by increasing sympathetic nervous system activity, which can lead to a faster heart rate. In some cases, a specific type of SVT called reentrant SVT may be triggered by a premature heartbeat.
-
While often asymptomatic, exercise-induced SVT can cause palpitations, dizziness, lightheadedness, shortness of breath, or chest pain.
-
If SVT episodes are frequent, prolonged, or accompanied by other symptoms like chest pain, shortness of breath, or fainting, it's important to consult with a doctor.
-
Treatment options for SVT include medication to control heart rate, cardioversion (using an electric shock to restore normal rhythm), or procedures like radiofrequency ablation to target the electrical pathway causing the arrhythmia.
-
While exercise can be a trigger for SVT, it's generally not something to avoid. WebMD recommendsconsulting with a doctor to determine an appropriate exercise plan and be mindful of potential triggers like intense exercise.
