Hospital Affiliations and Procedure Scheduling
Hospital affiliations and procedural locations may vary by insurance, scheduling, hospital privileges, and clinical need. Please call Cardioclinic to confirm where your consultation, testing, or procedure may be scheduled.
Patient-Centered Care Philosophy
Heart rhythm symptoms can be stressful. Palpitations, racing heartbeat, fainting, AFib alerts, and abnormal test results often leave patients with urgent questions about risk, treatment, and next steps.
Dr. Khan’s approach focuses on listening carefully to symptoms and concerns, reviewing risk factors and prior testing, explaining rhythm findings in clear language, creating a personalized treatment plan, coordinating testing when needed, discussing medication and procedure options, and supporting long-term prevention and follow-up care.
At Cardioclinic, the goal is not only to treat rhythm problems, but also to help patients understand their condition and feel confident in their care plan.

Heart Rhythm and Electrophysiology Expertise
Cardiac electrophysiology is the area of cardiology focused on the heart’s electrical system. Patients may be referred to an electrophysiologist when they have irregular heartbeat symptoms, recurrent palpitations, AFib, atrial flutter, SVT, ventricular tachycardia, unexplained fainting, abnormal rhythm testing, or device-related concerns.
Dr. Khan’s rhythm-focused care may include evaluation of complex cardiac arrhythmias, catheter ablation consultation, pacemaker and ICD care, long-term rhythm monitoring, and personalized cardiovascular risk reduction.
AFib and Arrhythmia Care With Dr. Zaka Khan
Dr. Khan helps patients with AFib understand whether AFib is present, how often it occurs, whether rhythm monitoring is needed, whether rate control or rhythm control may be appropriate, how stroke risk should be evaluated, whether blood thinner therapy should be discussed, and whether cardioversion, ablation, or device evaluation may be appropriate.
Diagnostic Testing for Heart Rhythm Symptoms
Patients with palpitations, irregular heartbeat, dizziness, fainting, AFib concerns, or abnormal wearable alerts may need rhythm-focused testing.
EKG / Electrocardiogram
An EKG records the electrical activity of the heart during a short test and may help detect AFib, slow rhythm, fast rhythm, or other abnormal rhythm patterns.
Holter Monitoring
Holter monitoring records the heart rhythm over a longer period and may help detect rhythm problems that do not appear during a short office visit.
Learn more about Holter monitoring
Event Monitoring
Event monitoring may be used when symptoms occur less frequently and need longer-term rhythm tracking.

Echocardiogram
An echocardiogram uses ultrasound to evaluate heart structure and function, including pumping strength, chamber size, and valve function.
