What Is The Energy Output Of A Defibrillator
What is thachy_brady syndrome?Is it the cause of pacemaker implantation by the kind of pacemaker used? Single or dual chamber.Thank you
Fast and slow!: Tachy-brady means sometimes the heart goes too fast and other times too slow. We need a pacemaker to prevent the slow beats so we can more safely give medication to control the fast beats. The type of pacemaker depends on what type of rhythms are involved. Usually it's dual chamber unless someone is in atrial fibrillation all the time. ...Read more
The sinus node: The sinus node is a group of specialized pacemaker cells that is located in the upper right atrium. These cells react to circulating chemicals, such as adrenaline, and there are nerve connections from the brain that modify the heart rate in response to the body's needs. ...Read moreSee 1 more doctor answer
It's quick: When you come to the lab, out give you some Lidocaine in your skin which stings and burns for a moment. After that, you'll feel some pressure and pulling as we make a space for the pacemaker. There will be a little bit of pressure as we put in the sheaths to attach wires to the heart. You may feel your heart race as we test the wires, and after a few stitches, it will all be over. ...Read moreSee 1 more doctor answer
Devices for rhythm: Pacemakers are medical devices implanted under the skin and connected to leads inserted through veins into the chambers of the heart. By sending out a small electrical impulse the pacemaker can restore heart rhythm. The most common use for a pacemaker is for a very slow heart beat to restore rhythm. They may be either single or double lead pacemakers determined by patient need. ...Read moreSee 1 more doctor answer

Is a v fib, where the bottom of the heat flutters and the blood does not go to the rest of the body, considered a heart attack?
No: Ventricular fibrillation is a type of arrhythmia (abnormal heart rhythm) that can result from a heart attack. A heart attack implies a blockage of one of the coronary arteries resulting in lack of blood supply (and oxygen) to a portion of the heart. However, ventricular fibrillation has many other potential causes. ...Read moreSee 2 more doctor answers
Artificial pacemaker: Artificial (implantable) pacemakers are mostly regulated by a sensor that recognizes motion. It's similar to the sensor that changes your phone/ipads display from portrait to landscape, based on the direction of the device. There are other sensors, such as ones that measure the density of blood in the heart and chest motion (simulating breathing). Get your routine pacemaker maintenance checks. ...Read moreSee 1 more doctor answer
None: I assume you're referring to an AED - automatic external defibrillator. Unless you live in a cardiac care unit, an airport, or some other large public area, you'll pay a lot of money and never use it. It won't benefit YOU since someone else has to apply it. It must be tested and certified annually (another expense). (If you're talking about an INTERNAL defibrillator, disregard all of the above) ...Read more
What is the normal urine output in a case of hypovolemic shock? What are the doctors looking for?
Oliguria: Oliguria or low urine output is defined as less than approximately 350 cc/day. Anuria or absence of urine is less than 50 cc day. Either of these conditions can occur in hypovolemic shock. Treatment of this condition usually requires large amounts of IV fluids and i usually would like to see at least 100/cc of urine per hour to indicate adequate repletion of volume losses. ...Read more
Improvement maybe: If the procedure is successful, the palpitations will not recur. Of course, if the procedure is not a success, the symptoms will recur. Then there are compkications such as stroke, tamponade (bleeding into the sac around the heart), and injury to blood vessels which may cause bleeding and may require surgical repair. ...Read moreSee 1 more doctor answer
What is the most effective test to determine the presence of old heart attack to any ventricle of the heart?
Old heart attack: You should see a cardiologist. One thing they might do is an echo car diorama where they have a, look at the actual motion of the heart muscle and the flow of the blood through the heart. That should show if any part of the heart is not working right, like for instance from damage due to a heart attack. ...Read more
What happens if a man has a cardiac reserve of 400% and maximum cardiac output is 20 l/min, what is his resting cardiac output?
Great question: Sounds about normal for average individuals, but low for highly trained athletes. Resting cardiac output generally around 5 liters/min and 400% is 4 x the resting output. Not sure how you tested this, but it sounds about right for an average, healthy individual. If you are a highly trained athlete, or if you have symptoms of fatigue or shortness of breath, you may want to speak to a physician. ...Read more
