Test 2.4 Flashcards
What are some intrinsic factors of SCD
Hypertrophic cardiomyopathy(HCM) Congenital coronary artery anomalies
What percent of deaths have no structural deformity and why
2% and because there was a disruption in the electrical system at the cellular level
What percent of SCD comes from HCM and what does it include
33% and included asymmetric left ventricular hypertrophy
How many people does HCM exist in the general pop and competitive athletes
1 in 500 for gen. Pop and 1 in 5,000 for athletes
What percent of ECG will be abnormal for patients with HCM
95%
What is the second leading cause of SCD in athletes and what is the percent of death
Coronary artery anomalies and 17%
Transthoracic ECG can indentify coronary artery origins in what percent of patients
80-97%
What percent does myocarditis account for in SCD
6%
What are S & S for myocarditis
Flu-like
Congestive
Exercise intolerance
Prodormal viral illness
What percent of arrhymogenic right ventricular cardiomyopathy consist for SCD
4%
What is the leading cause of SCD in northeastern Italy
Arrhymogenic right ventricular cardiomyopathy
What is the best way to see ARVC
On cardiac MRI or histolgic analysis
What is hyperoxia
Condition in which an excess of oxygen reaches the cells
What victims is hyperoxia usually found in
Carbon monoxide victims
What percent of ion channels disorder lead to SCD and what is the most common type
3% and long QT syndrome
What is ion channel disorder
A primary electrical issue of the heart predisposing the individual to potentially lethal ventricular arrhythmias
Catecholamingeric polymorphic ventricular tachycardia (CPVT) is a ____________
Stress induced ventricular arrhythmia
What is the most common inherited disorder of connective tissue that affects multiple organ systems
Marfans syndrome cause by rupture in aorta
What are some extrinsic factors for SCD
