What heart conditions is propafenone used for?
heart arrhythmias usually of the more dangerous kind. Like ventricular tachycardia and ventricular fibrillation.
Is atrial fibrillation worse that ventricular fibrillation?
No, ventricular fibrillation is worse than atrial fibrillation. This is because the ventricle is the chamber responsible for the main force pumping the blood out of the heart. If this contraction is not coordinated (like when fibrillation occurs), then the heart will not be able to function and consciousness will be lost within a few seconds. Ventricular fibrillation may result from electric shock, major myocardial infarct or some anaesthetic drugs. Resuscitation is usually possible by applying an electric shock (defibrillation) - which causes all cells to enter the refractory period and gives the sinoatrial node a chance to resume its normal pacemaker activity.
What is a couplet in cardiology?
A couplet in cardiology refers to two consecutive premature ventricular contractions (PVCs) on an electrocardiogram. It is considered a type of ventricular arrhythmia and may increase the risk of developing more serious arrhythmias like ventricular tachycardia or ventricular fibrillation. Treatment may be necessary depending on the patient's overall clinical situation.
Why is adrenaline used?
It can be used if you are going into anaphylaxis- a really bad allergic reaction. It is also used in heart-related emergencies, like with Ventricular tachycardia or fibrillation, or to try and restart the heart in asystole.
What two heart rhythms are considered lethal?
There are a variety of them. There's ventricular fibrillation, ventricular tachycardia, and of course "asystole". There are also other lethal dysrhythmias that can deteriorate into forms of the aforementioned rhythms like 3 AV Block, agonal, Accelerated IVR, etc. http://skillstat.com/Flash/ECGSim531.html check out this website and look at some of the rhythms. click play when it comes up.
What are the differences between synchronous and asynchronous cardioversion?
Synchronus cardioversion is when shock is delivered on QRS portion of the heart cycle (time when ventricle depolarises). It is used when pulse is present in a patient usually greater than 150/min and sign and symptoms usually of tachycardia. Like in Atrial Fibrillation. But in case of asynchronus cardioversion shock can be given at any time of heart cycle. Pulse is absent like in Ventricular Fibrillation.
What does it feel like to be floating?
There are several things these symptoms could represent, including atrial fibrillation or episodes of ventricular tachycardia. These could be symptoms of cardiac ischemia or an effect of a medication you are taking. I would recommend seeing your doctor for further evaluation.
What type of pattern will electro-cardiogram show for sudden cardiac arrest?
In sudden cardiac arrest elctro-cardiogram will show two types of patterns. One is straight line indicating that heart is stopped. Second is small vibration like pattern indicating ventricular fibrillation. You have to give intracardiac adrenaline in first and direct current shock in second.
What are some common heart diseases?
Some of the more common are:Myocardial infarction (heart attack, ischemic heart disease),CHF (congestive heart failure),cardiomyopathy (inflammatory or infectious disease of the muscles of the heart),hypertensive heart disease,heart valve leaks, prolapse and inefficiency,congenital heart defects in infants,arteriosclerotic heart disease (ASHD, aka hardening of the arteries),bundle branch block,sick sinus syndrome,rheumatic heart disease,coronary artery stenosis and occlusion,heart arrhythmias, like atrial fibrillation and ventricular fibrillation.
How does too much caffeine in a day kill a person?
Caffeine increases your blood pressure and heart rate. It stimulates the cardiovascular system. If too much caffeine is present, it can stimulate the heart to the point of ventricular fibrillation, which can lead to rapid cardiac arrest and death. It is very difficult to overdose on caffeine using coffee, but caffeine pills are easy to overdose on and deaths have been reported from caffeine pills. They should be used with caution. One or two of the average caffeine pill should be enough for most people to get a coffee-like buzz.
What does a ventricular assist pump look like?
hii use a small ecmo without a membrana
What does palpitant mean?
Palpitation is a "symptom". A person is aware of his or her heart beat. When you run for a while and stop you become aware of your heart beat for sometime. That is palpitation. When you are nervous, at times you become aware of your heart beating, that is palpitation. In certain Heart diseases like atrial fibrillation, one can get palpitation.
