Question : I admit to drinking a lot of coffee. Would only that be causing irregular and rapid pulse?

Detailed Answer:
Hi and thank you for asking!
I read your query and understood your concerns.

Drinking a lot of coffee alone may be responsible for rapid pulse and arrhythmia. However, other causes should be excluded including:
- Anemia
- Hormonal imbalance (hyperthyroidism)
- Heart failure.

This is why I would like to recommend doing the following examinations:
- Blood work (including hormonal balance)
- ECG
- Cardiac echo
- Holter monitoring

Hope this willl be of help!
Wish you health!
