EKG Interpretation, part 2: Placement of EKG leads, Heart Conduction System and EKG Basics

EKG Interpretation, part 2: Placement of EKG leads, Heart Conduction System and EKG Basics

by Cathy Parkes

In this video, Cathy explains where to place the 10 electrodes when performing a 12 lead EKG, the steps in the Heart Conduction System, and how those steps are reflected on an EKG waveform. Cathy also goes over some important EKG basics, including: duration of small boxes and big boxes, and expected amplitude and duration of the EKG components.

EKG Interpretation, part 3: Analysis of Heart Rhythm, Heart Rate, P wave, PR interval and QRS complex

EKG Interpretation, part 3: Analysis of Heart Rhythm, Heart Rate, P wave, PR interval and QRS complex

by Cathy Parkes

In this video, Cathy goes through the key steps in analyzing an EKG strip: determining the heart rhythm (regular vs. irregular), determining the heart rate using small box method vs. big box method vs. 6-second strip method; P waves; PR intervals; and QRS complexes.

EKG Interpretation, part 4: Natural Pacemakers of the Heart - Key Differentiating Factors

EKG Interpretation, part 4: Natural Pacemakers of the Heart - Key Differentiating Factors

by Cathy Parkes

In this video, Cathy describes the different natural pacemakers in the heart: the SA node, the atria foci, the junctional foci, and the ventricular foci. Cathy describes the inherent rate and key characteristics of each pacemaker, which will help you understand and differentiate the different dysrhythmias.

EKG Interpretation, part 5: Sinus Rhythms

by Cathy Parkes

In this video, Cathy describes Sinus rhythms, including: Normal Sinus Rhythm, Sinus Bradycardia, Sinus Tachycardia, and Sinus Arrhythmia. Cathy explains how to analyze each rhythm and talks briefly about interventions for the different arrhythmias.

EKG Interpretation, part 9: Atrioventricular Blocks (AV Blocks)

EKG Interpretation, part 9: Atrioventricular Blocks (AV Blocks)

by Cathy Parkes

In this video, Cathy discusses the 4 types of AV Blocks: 1st degree AV Block, 2nd degree AB Block types 1 and 2, and 3rd degree AV Block. Key characteristics of each type of block are covered, along with silly ways to remember the differences between the blocks.

EKG Interpretation, part 10: Other EKG Abnormalities

EKG Interpretation, part 10: Other EKG Abnormalities

by Cathy Parkes

In this video, Cathy discusses EKG abnormalities, including: bundle branch blocks, sinus pauses, and escape beats. She also covers the key EKG abnormalities seen with electrolyte imbalances, cardiac disorders (angina, ischemia, pericarditis), and respiratory disorders (pulmonary embolism, COPD).

EKG Interpretation, part 11: Artificial Pacemakers, Tachycardia and Bradycardia

by Cathy Parkes

In this video, Cathy discusses synchronous vs. asychronous artificial pacemakers, and how to identify atrial pacing, ventricular pacing, and AV packing on EKG strips. She explains the causes, symptoms and interventions for bradycardia and tachycaria dysrhythmias.
