From the Guidelines
The next step in management for this 56-year-old female with tachycardia, intermittent chest tightness, and EKG showing right atrial abnormalities and nonspecific ST-T changes should be a thorough clinical history and physical examination to distinguish whether the palpitations are regular or irregular, as suggested by the guidelines for the management of patients with supraventricular arrhythmias 1. This approach is crucial in determining the type of arrhythmia and guiding further management. The patient's symptoms of tachycardia and intermittent chest tightness, combined with the EKG findings, warrant a detailed evaluation to rule out underlying cardiac pathology.
- Key points to consider in the clinical history include:
- The pattern of symptoms, including the number of episodes, duration, frequency, mode of onset, and possible triggers
- The presence of any arrhythmia-related symptoms, such as palpitations, fatigue, lightheadedness, or dyspnea
- The distinction between regular and irregular palpitations, as irregular palpitations may be due to premature depolarizations, AF, or multifocal atrial tachycardia (MAT)
- Further diagnostic testing, such as ambulatory cardiac monitoring with a Holter monitor or an event recorder, may be necessary to capture any arrhythmias that may be causing her symptoms, as suggested by the guidelines 1.
- Additionally, a cardiac stress test, preferably with imaging, could be considered to evaluate for underlying coronary artery disease and assess cardiac function during exertion.
- While waiting for these tests, the patient should be advised to avoid excessive caffeine, alcohol, and strenuous activity, and to report any worsening symptoms immediately.
- If the diagnostic tests reveal significant cardiac pathology, such as coronary artery disease or arrhythmias, further management might include cardiac catheterization, antiarrhythmic medications, or other interventions as needed.

Next Steps in Management
The patient's current complaint of tachycardia and intermittent chest tightness, along with normal bloodwork and EKG results showing sinus rhythm with right atrial abnormalities and nonspecific ST-T abnormalities, requires further evaluation.
- The EKG results indicate the presence of some cardiac abnormalities, but the nonspecific ST-T abnormalities do not clearly point to an acute coronary syndrome 2.
- Given the patient's symptoms and EKG results, a stress echocardiography (SEC) may be considered to further assess cardiac function and potential coronary artery disease (CAD) 3.
- The use of dobutamine stress echocardiography has been established as a technique to assess myocardial viability and CAD, and may be useful in this patient's evaluation 4, 3.
- It is essential to interpret the EKG results in the context of the patient's clinical symptoms and consider other potential causes of the patient's symptoms, such as valvular heart disease or diastolic dysfunction 3.
- A stepwise approach to EKG interpretation, considering the patient's symptoms and medical history, is crucial in guiding further management decisions 5.
