Doctor thinks I have pneumonia.Started antiobiotics. Fever stopped. Heart rate very high (85-100). I'm worried, is it normal?

Doctor thinks I have pneumonia.Started antiobiotics. Fever stopped. Heart rate very high (85-100). I'm worried, is it normal?

See below: It would not be unusual for you to have a mild to moderate increase in pulse rate during early treatment for pneumonia. 85-100 is not a very high heart rate. The fact that your fever is better suggests your antibiotic treatment is effective. If you are feeling better don't worry about a pulse of 85-100. It will return to your baseline after resolution of your pneumonia and any deconditioning. ...Read more

2nd period starting withing 30 days. Feel very weak and exhausted. 1st period lasted 2 days then completely stopped. Heart palps as well with this.

2nd period starting withing 30 days. Feel very weak and exhausted. 1st period lasted 2 days then completely stopped. Heart palps as well with this.

My guess is your: irregular menses are the result, not the cause, of your ill feeling. Your weakness and exhaustion may be signs of some illness, especially viral, you are fighting. Often, these are the only symptoms without upper respiratory or GI symptoms. Viral syndromes often will disrupt the menstrual cycle. Rest, don't overdo, eat healthfully, stay hydrated. Consider a Doctor visit to help sort this out. ...Read more

What happens when you shock a patient with asystole? What is happening to the heart?

What happens when you shock a patient with asystole? What is happening to the heart?

Asystole: When a patient has asystole, the heart is not contracting and has no significant electrical activity. When you deliver a shock, it may stimulate return of electrical activity and hopefully mechanical activity or it may not. What is happening is the heart is dying and the shock is an attempt to reverse that process. ...Read more

Can you tell me if throughout asystole, is adrenaline injected directly into the heart?

Can you tell me if throughout asystole, is adrenaline injected directly into the heart?

Not any more: That was part of the older protocol - makes for very dramatic television! The modern approach is to inject it into a running IV - central line is best but peripheral IV is acceptable. There were too many lacerated coronary arteries and right ventricles with tamponade when direct injections were used. (especially while CPR is going on). ...Read more

Impalpable radial pulse today at times. Now trying to sleep and radial pulse disappears for a second followed by adrenaline surge and return of pulse. Asystole poss in healthy (pots) heart? Or low bp

Arrythmia.: The missing pulse followed by a strong one occurs with an abnormal, premature beat. This type of arrhythmia is common in otherwise healthy people, and is ok as long as it's rare and there are no other symptoms. Smoking (and caffeine) may be cause. If associated with chest pain, shortness of breath, lightheadedness or dizziness it could be dangerous. If frequent, your doctor should do an ecg. ...Read more

How do you know the heart will restart are been stopped for bypass surgey. What if it didnt?

How do you know the heart will restart are been stopped for bypass surgey. What if it didnt?

If no restart, death: The heart is stopped for this surgery using potassium and cold fluids. After bypass, the heart now has appropriate blood flow (the reason for the surgery). The heart is then rewarmed. It may restart on its own. If not, the surgeon may use special tools to shock the heart to regain function. This would be typical. If the heart is severely impaired going into surgery, recovery may be a problem. ...Read more

My heart stopped for a couple of seconds? Is this serious?

My heart stopped for a couple of seconds? Is this serious?

How did you know?: The key here is - how did you know? If you were told on the basis of a monitor and you had no symptoms with an otherwise normal exam, it's nothing. Many people drop to 30 during sleep (30 means that your heart is beating once every 2 seconds). Pauses up to 5 seconds can be normal. However, the big picture is important. Electrical block on your EKG would make it potentially more serious. ...Read more

My heart stopped as a baby would i as a adult have side effwcts?

My heart stopped as a baby would i as a adult have side effwcts?

Heart stopped: That depends on a lot of things. It is possible that there was some small abnormality that caused your heart to stop as a child, and to not have any long lasting effects as an adult. However, it was probably some more than just a minor issue for it to stop your heart, so chances are that you might have some issue. I would see a cardiologist and get a 2d echo to be safe. ...Read more
