My husband was diagnosed with High Blood Pressure about 18 months ago and was given a tablet called Lisinopril for it. Just recently he has developed what the doctor said was panic attacks. He is very laid back and never worries about anything and wakes up during the night with his heart racing and a tightness in the chest. The only thing we can put these panic attacks down to is that it might be a side effect from the tablets. Anyone out there with any similar experience. He is only 47.
