MRI - Device Present: Some heart pacemakers and other devices are now being engineered to be MRI safe. Most stents are safe after a 6 to 12 week wait for the vessel wall lining to cover them with a fresh layer of cells. The implanting MD can tell you if it is safe to have a MRI. In all cases ...Read more

Shock (Definition)

A condition in which a person cannot circulate enough blood (carrying oxygen and nutrients) to the vital organs in the body. If shock persists, various parts of the body will stop working, and the person will die. Causes of shock include injuries, excessive bleeding, heart failure, infections, chemical imbalances, ...Read more

How often does the electric shock revive someone who had a cardiac arrest?

How often does the electric shock revive someone who had a cardiac arrest?

Reset conduction: You heart has an electrical conduction system that controls how the heart muscle contracts. Often in cardiac arrest that conduction system is sending disordered electrical signals. The shock sometimes given during cpr/acls is an attempt to "reset" the conduction system so the electric signals go back to the proper order. ...Read more

Can someone who has had a cardiac arrest and heart stops continue to breathe?

Can someone who has had a cardiac arrest and heart stops continue to breathe?

Usually not: Once the heart arrests, the rest of the body begins to shut down until circulation is restored. Which is why its so important to get an AED or shock the heart using a defibrillator. Even if breathing continues, it is useless because there is not blood perfusing the lungs to pick up the oxygen and take it back to the heart. ...Read more

Pain in chest. Is there a test that will confirm whether I had a cardiac arrest?

What benefit does the implantable cardioverter-defibrillator give to patients who have had a cardiac arrest or heart attack?

What benefit does the implantable cardioverter-defibrillator give to patients who have had a cardiac arrest or heart attack?

It may prevent death: Implantable cardioverter-defibrillators (icds) are used to treat ventricular tachycardia or ventricular fibrillation, which if untreated, may cause a fatal cardiac arrest. Icds can often quickly treat these conditions before permanent brain or heart damage can be done. Icds are not used to treat or prevent heart attacks, which are a "plumbing" issue. ...Read more

Can breaking up with someone cause cardiac arrest?

Can breaking up with someone cause cardiac arrest?

Yes, but not likely.: Patients with coronary artery disease + other heart disease r @ risk 4 stress induced arrythmias. These r irregular heart rhythms, the most serious of which is cardiac arrest. So, yes, the stress of a breakup, or major loss of any kind may contribute 2 cardiac arrest in a patient with heart disease. This would b unlikely in a healthy person, but go c a doc if u do not feel right. Dr mike. ...Read more
