Brief Answer:
The cause seems to be atenolol

Detailed Answer:
Hi
Thanks for your query.

Loss of libido, muscle weakness are uncommon side effects of beta-blockers. Atenolol is a betablocker. If its medicine induced, then these symptoms will disappear within 1 month of stopping medicine.

Palpitation is a symptom. If there is no underlying cause found on tests, there is no point in taking atenolol for so long.

Kindly check with your doctor if you can stop atenolol.

Hope it helps. Let me know if I can assist you further.

Thanks for your kind reply. Whenever I tried to taper off the dose of Atenolol 50 mg gradually and discontinue following Doctor's advice of taking Metoprolol 25 mg in place of it, my palpitaion aggravated.The only way to get relief was to continue Atenolol again. thus it may be said that my body has become addicted to it.
In the light of facts that my Doppler ECO, ECG and TMT reports are normal and I have been using Atenolol for the last 22 years, I would like to know whether further continuance is advisable or its prolonged use will one day adversely affect my Cardiac output/ performance.
Thanking you.

Brief Answer:
Medicines are chemicals

Detailed Answer:
Hi again

Medicines are chemicals and these have effect on body.
Atenolol has been vastly studied. Most studies have shown its beneficial effect on failing heart. Yours is a normal heart. Palpitations maybe from another cause.
Atenolol can have cardiovascular adverse effects like low heart rate, peripheral vascular efficiency, postural hypotension, heart failure, AV Block, arrhythmia, angina. These have been listed in medical textbooks.

Palpitations can be tolerated with certain lifestyle measures like deep breathing, relaxation exercises, keeping busy in work, avoiding tea, coffee, alcohol, etc. You can try tapering the dose of atenolol over a few weeks to avoid sudden withdrawal.

Hope it helps.
