Effects of ranitidine and cimetidine on experimentally induced ventricular arrhythmias in anaesthetized rats. And actually, it’s excess histamine because of the widening of the blood vessels and the increase in the heart rate – and on a low histamine diet, the panic attacks have gone away,” she said. It’s only cardio that seems to do it, though – resistance training, like lifting weights (don’t overdo it), doesn’t appear to have that effect. Cardiac histamine receptors: their pharmacological consequences and signal transduction pathways.
