Right heart Enlargement Flashcards
(19 cards)
What is Right Atrial Enlargement (RAE)?
Enlargement of the right atrium
RAE can be identified through specific ECG characteristics.
What are the causes of Right Atrial Enlargement (RAE)?
- Right Ventricular Hypertrophy (RVH)
- Tricuspid valve disease
- Pulmonary valve disease
- Pulmonary hypertension
- Chronic Obstructive Pulmonary Disease (COPD)
- Pulmonary emboli
Understanding these causes is crucial for diagnosing RAE.
What are the ECG characteristics of Right Atrial Enlargement (RAE)?
- Peaked P waves (>2.5mm) in Leads I, II, III
- Diphasic P wave in V1 with initial deflection larger than distal portion
The peaked P waves are referred to as P-pulmonale.
What is Right Ventricular Hypertrophy (RVH)?
Enlargement of the right ventricle
RVH can lead to specific changes in the ECG.
What are the causes of Right Ventricular Hypertrophy (RVH)?
- Pulmonary valve stenosis
- Tricuspid insufficiency
- Pulmonary hypertension
- Ventricular septal defect
Identifying these causes helps in managing RVH.
What are the ECG characteristics of Right Ventricular Hypertrophy (RVH)?
- Tall R waves in V1/V2
- Deep S waves in V5/V6
- Right Axis Deviation (RAD)
These characteristics can assist in diagnosing RVH.
What does Sinus Tachycardia with RAE/RVH indicate?
It indicates a possible enlargement of the right heart structures
Sinus tachycardia may be a response to underlying heart conditions.
Define Diphasic P wave.
Deflection both above and below the baseline
In RVH, the initial P wave deflection is taller than the distal portion, seen in V1.
What is the height of the P wave in Lead II for Right Atrial Enlargement (RAE)?
Greater than 2.5mm
This measurement is critical for diagnosing RAE.
What is a common cause for both Right Atrial Enlargement (RAE) and Right Ventricular Hypertrophy (RVH)?
Pulmonary hypertension
Recognizing this commonality can aid in clinical assessments.
What is Right Atrial Enlargement (RAE)?
Enlargement of the right atrium.
RAE can indicate underlying cardiovascular issues.
What are common causes of Right Atrial Enlargement (RAE)?
- Right Ventricular Hypertrophy (RVH)
- Tricuspid valve disease
- Pulmonary valve disease
- Pulmonary hypertension
- Chronic Obstructive Pulmonary Disease (COPD)
- Pulmonary emboli
Understanding these causes can help in diagnosing RAE.
What ECG characteristics are associated with RAE?
- Leads I, II, III: Peaked P waves (>2.5mm), known as P-pulmonale
- V1: Diphasic P wave with the initial P wave deflection larger than the distal portion.
These ECG patterns are crucial for identifying RAE.
What is Right Ventricular Hypertrophy (RVH)?
Enlargement of the right ventricle.
RVH can be a response to increased workload on the right ventricle.
What are common causes of Right Ventricular Hypertrophy (RVH)?
- Pulmonary valve stenosis
- Tricuspid insufficiency
- Pulmonary hypertension
- Ventricular septal defect
Identifying these causes is essential for treating RVH.
What ECG characteristics are associated with RVH?
- V1/V2: Tall R waves
- V5/V6: Deep S waves
- Right Axis Deviation (RAD)
These characteristics help differentiate RVH from other cardiac conditions.
What is a diphasic P wave?
Has deflections both above and below baseline.
In RVH, V1 shows an initial P wave deflection taller than the distal portion.
What is the significance of P waves in RAE?
Lead II P waves must be greater than 2.5mm.
This measurement is critical for diagnosing RAE.
What is a common cause for both RAE and RVH?
Pulmonary hypertension.
Recognizing this link can aid in understanding patient conditions.
