- Monomorphic ventricular tachycardia means that the appearance of all the beats match each other in each lead of a surface electrocardiogram (ECG).
- Scar related monomorphic ventricular tachycardia is the most common type and a frequent cause of death in patients who have survived a heart attack or myocardial infarction especially if they have weak heart muscle.
- RVOT tachycardia is a type of monomorphic ventricular tachycardia originating in the right ventricular outflow tract. RVOT morphology refers to the characteristic pattern of this type of tachycardia on an ECG.
- Polymorphic ventricular tachycardia, on the other hand, has beat-to-beat variations in morphology. This may appear as a cyclical progressive change in cardi ac axis, previously referred to by its French name torsades de pointes ("twisting of the points"). However, currently the term torsades is reserved for polymorphic VT occurring in the context of a prolonged resting QT interval.
- If the fast rhythm self-terminates within 30 seconds, it is considered a non-sustained ventricular tachycardia.
- If the rhythm lasts more than 30 seconds, it is known as a sustained ventricular tachycardia (even if it terminates on its own after 30 seconds).
I have a granddaughter that has this awful heart disease, and we have almost lost her three times. She went into heart failure with in hours after giving birth to her second baby which was almost four yrs. ago now (in December). Since all of this has happened we have heard or known someone that has had the same thing happened to them and also right after in 95% of cases the birth of a second baby! The doctors (for the most part) do not know about this, or are not familiar with this happening to young women that has given birth. Listening to the news and keeping up with this more now that it's happened in my family has definitely made all of us more aware of this and thereby we pay more attention to when we hear about it on the news or other programs. This heart disease can cause a host of other problems along with it...such as seizures that are no epileptic and or not regular pseudo seizures. I had no idea there were so many different types of seizures until this happened.
My granddaughter that's has this just lost a friend from the same thing because she wasn't diagnosed correctly! My granddaughter wasn't either in the beginning...and it's hard to find a doctor to listen and that will take the time to see what is going on. The Mayo Clinic in Scottsdale AZ. is where she was correctly diagnosed and has her surgery. We live in Texas but had to take her all the way there to get the help she needed! THIS IS VERY SAD, because she had gone to Trinity Mother Frances,
Presbyterian and Baylor hospitals. How very sad is that?
My granddaughter is still unable to work or take care of her two beautiful kids. She does try very hard to take care of her kids, as much as she possibly can. She does have some good days, but most of the time it's all she can do to help herself. She was 23 yrs. old when this happened and is now 27. Her faith has gotten her through and knowing that her belief in GOD is great, that he is there with her and her precious babies I feel is one of the main reasons my beautiful granddaughter is still here with us fighting as hard as she does!
I hope that this information helps someone.
