Can Heat Exhaustion Cause Rapid Heart Beats
YES: Dehydration causes decreased blood volume of circulating blood. For the heart to keep pumping the same amount of blood (cardiac output), the heart has to speed up therefore causing increased heart rate (tachycardia). When dehydration is extreme, heart rate can be very fast (>>100 bpm) causing 'palpitations' . I.V fluids may be needed to quickly restore blood volume or vascular collapse will occur. ...Read moreSee 1 more doctor answer

With more potent vaso and cardio active meds or a damaged heart, it is entirely possible. ...Read more
