Yes.: Dehydration can cause tachycardia (Fast heart rate). But this could be a sign of an irregular heart rate as well. Key is to make sure the rhythm is at regular intervals. if its not, then you have to worry about atrial fibrillation. http://amansawmd.com/2014/02/17/atrial-fibrillation-overview/
