Transient P' waves in a hyperkalemic cat: artifact or dissociation?
1Red Bank Veterinary Hospital, 197 Hance Avenue, Tinton Falls, NJ, USA.
Summary
This case study discusses a Sphynx cat with hypokalemia that developed hyperkalemia and abnormal electrocardiogram (ECG) findings, including transient P
Area of Science:
- Veterinary Cardiology
- Feline Internal Medicine
Background:
- Cervical ventroflexion, ataxia, and lethargy in a 15-year-old Sphynx cat were initially associated with hypokalemia.
- Administration of potassium supplementation led to severe hyperkalemia in the patient.
Purpose of the Study:
- To present electrocardiogram (ECG) findings in a cat experiencing electrolyte abnormalities.
- To discuss differential diagnoses for transient P' waves on ECG, including atrial dissociation.
Main Methods:
- Clinical presentation of a Sphynx cat with neurological signs and electrolyte imbalance.
- Electrocardiographic monitoring during hospitalization and electrolyte level assessment.
- Review of potential causes for abnormal P' waves, such as atrial dissociation and artifacts.
Main Results:
- Transient P' waves were observed on the ECG during induced hyperkalemia.
- The abnormal P' waves resolved as the cat's potassium levels normalized.
- Definitive diagnosis of atrial dissociation was not achieved due to unavailability of advanced diagnostic studies.
Conclusions:
- Transient P' waves on ECG in cats can be associated with hyperkalemia and may represent atrial dissociation or artifacts.
- Electrolyte monitoring and ECG interpretation are crucial for diagnosing and managing complex feline cardiac and metabolic conditions.

01:29Dysrhythmias III: Characteristics of Dysrhythmias
16
Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per...

01:30Cardiac Action Potential
1.9K
Cardiac action potentials are essential for proper heart function, enabling the rhythmic contractions needed for adequate blood circulation. Nodal cells and Purkinje fibers, specialized for electrical conduction, generate these action potentials.
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
