Is it normal for your heart to beat slow and hard for a few secs when startled?
Is it normal if you become really frightened and startled (like by a loud noise, or if you have a near-miss accident) for your heart to beat slow and hard for a few seconds (with shortness of breath) before it begins to beat hard and fast? or does everyone elses heart just immediately beat hard and fast? mine takes a few seconds of slow, hard beat if i get really startled before it speeds up to normal and during this time i get a lot of shortness of breath. i'm 29/m and had all cardiac tests done for an unrelated matter, but doc never saw this on any monitor because it only happens on the occasion that i get genuinely startled
