Question: hi...i take 240 mg diltiazem ER daily in the morning which I did today. I accidentally took another one at 5:30 this afternoon. Do I need to be worried about anything?

Brief Answer: You don't worry.You are perfectly safe. Detailed Answer: Hello XXXX Thanks for writing to XXXXXXX You shouldn't worry. Diltiazem dose varies according to disease conditions and second dose accidentally taken by you will not cause any problems.You have taken second tablet after sufficient time and it will not effect you. But you should be cautious about symptoms like lightheadedness,dizziness,fainting,breathing difficulty.Overdose may also lead to bradycardia(slow heart rate), hypotension(decreased blood pressure),heart block and cardiac failure.If you have any of these symptoms then you should consult your doctor immediately. Get well soon. Hope i have answered your query. Further queries are most welcome. Take Care Dr.Indu XXXXXXX

I was diagnosed by EKG with first degree heart block, but when I look at the symptoms, I think that I have many symptoms of second degree mobitz II heart block. I have been having unexplained tiredness and episodes of unexplained light-headedness. Also I get episodes of feeling my heart beating funn in my throat and chest. It beats consistantly and then skips and then continues and skips again.

35 years old born with a 3rd degree complete heart block. Have a pacer with lead replacment at which time the tip severed and continues to anchor alone in the heart along with the replacment lead. Very nervous about the tip and nothing attached. How can it be removed and if left what could happen.

Also had an eko and found I have a 35% EF - nervous about that as well with my heart block. Please advise

My boyfriend was recently diagnosed with Wolff-Parkinson-White Syndrome. I did some research, and discovered that he has nearly all of the symptoms of heart block and many of the symptoms of heart failure. Whenever he has an episode with his heart, he gets very dizzy, nauseous, has chest pain and cold sweats, and eventually has a blackout. Is there anything that I can do to alleviate his symptoms when they occur?
