Diagnostic Testing
Our diagnostic testing services provide fast, accurate, and reliable results to help identify medical conditions and support early intervention. We utilize advanced laboratory and imaging technologies to assess a wide range of health concerns, from routine screenings to specialized diagnostics. Whether you’re seeking clarity on symptoms or managing a chronic condition, our tests deliver the insights your healthcare provider needs to make informed decisions about your care.
Ambulatory Blood Pressure Monitoring
This non-invasive test records your blood pressure over 24 hours during your normal daily activities and sleep. It helps detect high blood pressure that may not show up during a single clinic visit and provides a more accurate picture of your cardiovascular health.
Electrocardiography (EKG)
An EKG is a simple and painless test that records the electrical signals in your heart. It helps diagnose abnormal heart rhythms, heart attacks, and other cardiac conditions by showing how your heart is beating in real time.
Treadmill Stress Testing
This test evaluates how well your heart performs under physical stress. You walk on a treadmill while your heart rate, rhythm, and blood pressure are monitored to assess for signs of coronary artery disease or abnormal heart function during exercise.
Cardiac Monitoring (Holter & Event Monitors)
Holter and event monitors are portable devices used to record your heart’s rhythm over extended periods—typically 24 to 48 hours or longer. They help detect intermittent arrhythmias that may not be present during a standard EKG.
Cardiac Stress Testing (SPECT & PET)
SPECT and PET scans are nuclear imaging tests that evaluate blood flow to your heart muscle during stress and rest. They provide detailed images to detect coronary artery disease and assess heart function with high accuracy.
Cardiac Ultrasound (Echocardiography)
Echocardiography uses sound waves to create real-time images of your heart. It assesses heart size, structure, function, and valve performance, and is essential in diagnosing heart failure, valve disease, and congenital conditions.
Electrical and Chemical Cardioversion
Cardioversion is used to restore a normal heart rhythm in patients with arrhythmias like atrial fibrillation. It can be performed using medications (chemical) or an electric shock (electrical), both under close medical supervision.
Loop Recorder (Implant/Explant)
A loop recorder is a small device implanted under the skin to continuously monitor heart rhythms for up to several years. It is especially useful for diagnosing unexplained fainting, palpitations, or silent arrhythmias.
Tilt Table Testing
This diagnostic test helps identify the cause of unexplained fainting (syncope). It monitors your heart rate and blood pressure while you lie on a table that tilts from horizontal to vertical, mimicking postural changes.
Pacemaker Implantation
Pacemakers are small devices implanted under the skin to regulate slow or irregular heartbeats. We offer advanced pacemaker options including Left Bundle Branch Area Pacing (LBBAP), leadless pacemakers, and Bi-Ventricular pacemakers for heart failure management.
Implantable Cardioverter-Defibrillators (ICDs)
ICDs are life-saving devices implanted to monitor and treat dangerously fast heart rhythms. We provide a full range of ICD options including transvenous, subcutaneous, extravascular, and Bi-Ventricular ICDs based on your specific needs.
Catheter Ablation of Arrhythmias
Catheter ablation is a minimally invasive procedure that uses thermal (radiofrequency) or non-thermal (cryoablation, pulsed field) energy to destroy areas of heart tissue causing abnormal rhythms such as atrial fibrillation, SVT, or VT.
Lead Extraction
When pacemaker or defibrillator leads become infected or malfunction, lead extraction may be necessary. This delicate procedure is performed by experienced specialists using advanced tools to safely remove the leads.
Left Atrial Appendage Occlusion (LAAO)
LAAO is a minimally invasive procedure for patients with atrial fibrillation who cannot take long-term blood thinners. It involves implanting a device to close off the left atrial appendage, significantly reducing stroke risk.
Device Clinic with Remote Monitoring & Follow-Up
Our dedicated device clinic provides continuous care for patients with pacemakers and ICDs. Remote monitoring allows us to track your device’s performance and detect issues early, reducing the need for frequent in-person visits.

Having newly experienced cardiac issues, I asked a friend to recommend a cardiac specialist, and Dr. Kani was first and only on her list. As I walked up to the office and was greeted by beautiful flowers, I knew I was in the right place. Each person that performed tests was thorough, kind, and helpful.
