What Causes Frequent Urination With Rapid Heart Rate?
Your symptoms seem to be related to a paroxysmal atrial tachycardia
Detailed Answer:
Hello!
Welcome and thank you for asking on HCM!
I understand your concern and would explain that your symptoms seem to be related to a paroxysmal atrial tachycardia.
This is a type of cardiac arrhythmia which is associated with an excessive amount of urine in a short period, usually coinciding with the episodes of tachycardia.
Do you have any other symptoms like dizziness, lightheadedness, chest discomfort, etc, besides palpitations?
What are your blood pressure values during these episodes?
I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x ray study and some lab tests:
- complete blood count
- blood electrolytes
- fasting glucose
- kidney and liver function tests
- thyroid hormone levels (for possible thyroid dysfunction)
- cortisol plasma levels (adrenal gland function)
- blood osmolarity
- urine osmolarity, etc.
An ambulatory 24-48 hours ECG monitoring and a cardiac ultrasound are necessary to examine your cardiac function and rule in/out a cardiac arrhythmia.
Hope to have been helpful!
Feel free to ask any other questions, whenever you need!
Best regards,

I wonder if it this particular episode could be related to a bad night I just had of a nightmare followed by a panic attack and very little sleep. I have a great deal of anxiety these days with little sleep.
Anxiety could be a possible cause.

Hi again!
Having palpitations (racing heart) during excessive urination may have several explanations.
Anxiety and its associating sleeping disturbances (like nightmare, etc.) are an important source of cardiac tachycardia, but this doesn't mean you are suffering from any heart diseases. Properly addressing the anxiety component will resolve also such vegetative complains.
Sometimes, an excessive urination may be associated with orthostatic intolerance (due to urinary bladder mechanoreceptors over-stimulation); in such case tachycardia, relative hypotension, and even syncope are possible clinical expressions. In other instances, tachycardia is the only obvious vegetative implication.
But, as your current complains are only occasional, no related to any chronic disorders and no typical symptomatology is present, the only underlying cause remain anxiety.
Nevertheless, I recommend you performing the above mentioned medical tests to rule out other possible reasons.
Wishing you good health!
