Karen M. Marzlin – EKG Mastery: EKG Variants and Myocardial Mimics
ECG interpretation is based on comparison to the normal ECG. In this session you will learn normal ECG variants and myocardial mimics because their interpretation often leads to a wrong diagnosis. You will learn how drugs and electrolyte imbalances affect the ECG and be able to better understand the clinical presentation of your patient and provide for rapid and life-saving interventions.
OUTLINE
Variants
- Early repolarization
- Persistent T wave inversion
- Additional normal variants
Mimics
- Pericarditis
- Pulmonary embolus
- Aortic dissection
- CNS disease
Drug and electrolyte effects
- Digoxin
- Antiarrhythmics
- QT prolonging agents
- Potassium
- Calcium
OBJECTIVES
- Describe the characteristics of ST segment elevation associated with early repolarization.
- Differentiate pericarditis from myocardial infarction by ECG and clinical criteria.
- Identify 3 specific ECG findings that may be associated with pulmonary embolus.
- Discuss ECG and clinical implications of antiarrhythmic pharmacology and other medications affecting ventricular repolarization.
- Recognize and correlate electrolyte abnormalities with anticipated ECG findings.
What is health?
The word health refers to a state of complete emotional and physical well-being. Healthcare exists to help people maintain this optimal state of health.
According to the Centers for Disease Control and Prevention (CDC), healthcare costs in the United States were $3.5 trillionTrusted Source in 2017.
However, despite this expenditure, people in the U.S. have a lower life expectancy than people in other developed countries. This is due to a variety of factors, including access to healthcare and lifestyle choices.
Good health is central to handling stress and living a longer, more active life. In this article, we explain the meaning of good health, the types of health a person needs to consider, and how to preserve good health.
In 1948, the World Health Organization (WHO)Trusted Source defined health with a phrase that modern authorities still apply.
“Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.”
In 1986, the WHOTrusted Source made further clarifications:
“A resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities.”
This means that health is a resource to support an individual’s function in wider society, rather than an end in itself. A healthful lifestyle provides the means to lead a full life with meaning and purpose.
In 2009, researchers publishing inThe LancetTrusted Source defined health as the ability of a body to adapt to new threats and infirmities.
They base this definition on the idea that the past few decades have seen modern science take significant strides in the awareness of diseases by understanding how they work, discovering new ways to slow or stop them, and acknowledging that an absence of pathology may not be possible.
