Can sinus rhythm be pulseless

Yes, sinus rhythm can be pulseless in certain conditions, such as in cases of severe hypotension or cardiac arrest. While sinus rhythm indicates that the heart's electrical system is functioning normally, it does not guarantee effective blood circulation. If the heart is not generating sufficient contraction strength or if there is severe obstruction in blood flow, a person may have a sinus rhythm without a detectable pulse. This condition requires immediate medical intervention.
