        <title>Prolonged high heart rate</title>
        <description> I was out walking on a very cold day and did well for first hour but  into second hour my heart rate shot up to 200; unfortunately I was a good distance away from home so would walk and rest. It appears my supraventricular tachycardia broke through my beta Blockers. Was frightening to say the least. I seem to have recovered; heart rate has been normal for me. I was diagnosed in October 2023 with AFI. My AFIB burden is less than 2%.

Any and all thoughts appreciated.</description>

            <description><![CDATA[ Maybe 10 days after my first afib episode 20+ years ago, I had another episode &amp; decided to take a walk around downtown with a heart rate monitor record.  I was walking very fast and my heart rate was about 145 BPM.  I was going across the street and then I needed to sprint to get out of the way of a car.  This pushed my heart rate to 230 BPM.  It dropped a bit when I slowed down on the sidewalk, but then I tried the sprint again (I don&#039;t recommend you try this) and actually converted the episode. It was definitely afib and not flutter.  I have subsequently pushed it to 230 during other afib episodes as well (again, I&#039;m not suggesting this is a good idea).]]></description>

            <description><![CDATA[ Quite often an HR higher than about 170 or so, some variation, is as likely to be flutter as AF.  Happened to me once.]]></description>

            <description><![CDATA[ Have you experienced this before? Have you been diagnosed with SVT or some other type of tachycardia other than afib?]]></description>
