Final answer:
The client with palpitations and a radial pulse of 122bpm, and 'saw-tooth' waves on the ECG most likely has atrial flutter. This arrhythmia is characterized by rapid, regular atrial contractions reflected in the distinctive flutter waves on an ECG. Proper diagnosis and management are critical and may involve medications or procedures.
Step-by-step explanation:
The cardiac rhythm most likely causing the client's symptoms of palpitations and a palpable radial pulse of 122bpm, and showing “saw-tooth” waves between each QRS complex instead of normal P waves on the cardiac monitor, is likely atrial flutter (Option C).
This determination is based on the characteristic pattern on the electrocardiogram (ECG) which shows the signature “saw-tooth” waves, known as flutter waves, that indicate a single reentrant circuit within the atrium causing rapid, regular atrial contractions.
The flutter waves are typically seen in a 2:1 or 3:1 pattern, where for every flutter wave there are two or three QRS complexes respectively. Communicating effectively with professionals about arrhythmias, recognizing abnormal electrical patterns on an ECG, and understanding the corresponding changes in heart rate (pulse) are vital for proper diagnosis and management. Atrial flutter can lead to symptoms such as dizziness, shortness of breath, and chest pain, similar to those seen in other types of supraventricular tachycardias, but the ECG features are distinctive. Treatment for atrial flutter may include medications, procedures like electrical cardioversion, or ablation therapy.
