Hi XXXXXXX,
Welcome to XXXXXXX forum.

Feeling fast heart rate is called as "Palpitations".
Palpitations may be due to heart problem or due to hormonal problem.
Heart problem may be in form of conduction defects and missed beats.
Hormonal problems may be hyperthyroidism, pheochromocytoma and cushing's syndrome.

You should consult with XXXXXXX medicine speacialist and should go for thorough check up.
You should go for electrocardiography on priliminary basis to rule out any heart related disease.
You should also go for thyroid profile, serum epinephrine & norepinephrine level and vanniyl mandelic acis level, serum ACTH level.
You can also go for electrophysiological studies of heart.
If all these investigations are normal then there may be also be possibility of panic attacks also, as you are already suffering from PTSD and GAD.
You should also consult with psychiatrist.
Treatment depends on the diagnosed disease.
Hope that helps.
Let me know if I can address any more concerns.
Take care,
Dr. Mayank Bhargava

Hi,
Any type of heart conduction disturbances may be associated with impaired blood supply to brain and may cause dizziness along with pounding sensation in head and eyes.
This may be a part of panic attacks also.

the other day when driving i skidded out on the ice and almost slammed into a truck coming the opposite direction. i was fine but my heart began beating slowly and pounding with the fear rather than faster. it took almost a minute for it to go back to normal and i was terrified.
is this normal? or is this something i should be worried about. i have heard about something called long QT syndrome, but do not know if this is a normal human reaction under intense sudden startled such as that, thanks

I am a 23 year old female, studying medicine. For past 8 months, i have been having some episodes of heart 'dysfunctions' that now have turned constant. I need help in knowing what is the condition.
It started last may when one day i started feeling so weak that i just could not get up and was having a splitting headache, when i measured my BP was 90/55mmHg ( before it was always 120/80mmHg). I was having palpitations, bradycardia at times, tachycardia at times, extreme weakness, sweating ( especially on scalp) after sleeping after headache. I was also having light sleep.
Slowly, these episodes became constant. Now I am feeling weak all times, light headed if sitting or standing for long, headache (thumping with constant heaviness), inability to sleep, tightness in chest, chest pain sometimes, tachycardia at any normal activity (walking, doing some tidy up), BP is still low. I also get dry cough on breathing sometimes.
So i got a holter done for 24 hours, got following:
- sinus tachycardia( 110- 120) almost all day with some normal rate in between, my heart rate dropped to 50 in middle of night ( reason causing me to wake up from sleep and not to sleep again) and it remained like that for 3 hours
- average pulse -81
- my heart rate jumped to 179 per min when i climbed stairs ( 9 floors, easily climbed by others), breathing became laboured, headache with blacking out sensations ( i did not faint though)
- I have some abnormalities in lead I, II and III ( looks like left axis deviation as lead I is showing highest peaks and is moving away from III ) even the avL and avF looks weird, QTc>450ms is 47%, no ST deviation, no T wave abnormalities
I also have tachypnea (26-28 per min) and accentuation of Pulmonary part of second heart sound. I also have slight edema on my feet ( bluish tinge)
I also did a blood work up, I do not have thyroid problems or anemia
I need some advice on what i might be having, so as to proceed further on treatment.

About four years ago, I was diagnosed with ventricular tachicardia. I was given a catheter ablation to treat it, and it corrected an irregular heart beat that I've had since I can remember, but I still experience the rapid heart beats every now and again when Im out running or doing some other strenuous activity. Another thing that I've had since I can remember is excessive sweating, and I mean very excessive. What it takes for a normal person to sweat, it would take A LOT LESS for me. My question is, is the excessive sweating linked to the tachycardia? Of course, tachycardia causes the fast heart beat which in turn causes the sweating, but even when Im not experiencing the rapid irregular heart beats, I still manage to completely soak a t shirt when the guy next to me whose done the same amount of work is completely dry, aside from a few sweat beads on the forehead.

I was diagnosed with attrial flutters ( arrhythmia ) and the cardiologist did a cardio version and a subsequent EKG showed the condition was corrected. The doctor has me on Xarelto and a beta blocker . I feel fine and I am wondering if I can drink...

My husband is 80 years old and has been diagnosed with congenial heart dease. His heart is only pumping half the speed of a normal heart beat. And now his lungs are filling with fluid. He also has Alzheimer's.
