Cardiologist Serving Katy, Sugar Land, Greater Houston
Need heart rhythm monitoring beyond an office EKG or a Holter test? Mobile cardiac telemetry (MCT) records your heart rhythm continuously while you go about daily life and sends selected data to a monitoring center in near real time. At Advanced Cardiology, MCT is performed or arranged by our office to help diagnose irregular heartbeats that come and go.

Mobile cardiac telemetry (MCT) is a wearable heart monitor that records your rhythm continuously, often for up to several weeks. The device automatically detects certain abnormal rhythms and transmits recordings, usually through a cellular connection, to a monitoring center where trained technicians review them. Findings are reported to your cardiologist according to criteria set in advance, and you can also mark symptoms when you feel them.
The key difference from other monitors is speed of reporting. A Holter monitor records continuously but is analyzed only after you return it, and an event monitor saves recordings when you or the device trigger them. MCT combines continuous recording with near-real-time transmission, which can be helpful when your cardiologist needs to know about certain rhythms sooner.
MCT is not an emergency service. The monitoring center does not replace 911. If you have symptoms of a possible heart attack or stroke while wearing the monitor, call 911 right away.
Your data is interpreted by our board-certified cardiologist, Dr. Adnan Khalid, who reviews the telemetry reports together with your symptoms and history to reach a diagnosis and plan treatment that fits your needs.

Interventional Cardiology
Your cardiologist may recommend MCT when symptoms are intermittent or unexplained and have not been captured by a standard EKG or Holter monitor, or when certain rhythms need to be reported more quickly than other monitors allow.
Intermittent Palpitations or Irregular Heartbeats
Why it matters: Symptoms may occur sporadically and be missed on shorter tests.
How MCT helps: Continuous recording captures episodes as they happen, helping diagnose arrhythmias such as AFib, SVT or frequent premature beats. See our page on palpitations and irregular heartbeat.
Unexplained Dizziness or Fainting (Syncope)
Why it matters: These symptoms can be caused by sudden changes in heart rhythm or pauses, among other causes.
How MCT helps: Detects pauses, heart block or slow heart rates that might explain fainting. Learn more about dizziness and fainting evaluation.
Looking for Atrial Fibrillation
Why it matters: AFib can come and go and may cause few symptoms, yet it raises stroke risk.
How MCT helps: Continuous recording can detect brief AFib episodes. Read about atrial fibrillation care.
Monitoring Treatment
Why it matters: People who start or change heart rhythm medicines may need their rhythm checked.
How MCT helps: Provides rhythm data over weeks to help your cardiologist adjust therapy.
Chest discomfort and shortness of breath need a different first step. MCT tracks rhythm only; it cannot diagnose blocked arteries or heart failure. Call 911 for chest discomfort that lasts more than a few minutes or goes away and comes back; shortness of breath; discomfort in the arms, back, neck, jaw or stomach; a cold sweat, nausea or lightheadedness; or stroke signs such as face drooping, arm weakness or speech difficulty, even if they go away.
For symptoms that are not an emergency, call our office to ask about current availability at our Katy or Sugar Land office. Patients from Sugar Land, Richmond and nearby communities visit both locations.
Heart rhythm problems (arrhythmias):
MCT can detect irregular, fast or slow heartbeats such as atrial fibrillation (AFib), supraventricular tachycardia (SVT) or pauses. These findings help guide treatment plans, medication adjustments and, for some patients, decisions about devices such as pacemakers.
Silent or intermittent arrhythmias:
Because it records continuously, MCT can capture rhythm issues that come and go, including some that cause no symptoms.
Bradycardia or heart block:
Detects slow heart rates or conduction delays that could lead to fatigue, dizziness or fainting.
Premature beats and other rhythms:
Includes premature ventricular contractions (PVCs), ventricular tachycardia (VT) or other abnormal beats that may need further evaluation.
Effectiveness of treatment:
Shows how well medicines or procedures are controlling an arrhythmia.
MCT records the heart’s electrical rhythm only. It does not show blockages in the heart arteries, heart muscle strength or valve function; tests such as an echocardiogram or stress testing answer those questions. If no symptoms or rhythm changes happen during monitoring, the result may not explain occasional symptoms, and a longer option such as an implantable loop recorder may be discussed.
Based on your findings, your cardiologist may recommend additional testing, lifestyle changes, medication changes or other treatment.
If you have unexplained symptoms or need extended heart rhythm monitoring, MCT can provide information beyond what a standard EKG captures. Your cardiologist may suggest MCT if:
You have intermittent symptoms like palpitations, dizziness or fainting that don’t occur during office visits
An arrhythmia is suspected that requires extended monitoring
You have had abnormal or inconclusive EKG or Holter results and more data is needed
You have a higher risk of heart rhythm problems because of a prior heart condition or medication effects
Your cardiologist wants certain rhythms reported sooner than a Holter or event monitor would allow
The best choice depends on how often your symptoms happen, how serious the suspected rhythm is and your insurance coverage. Dr. Khalid will explain why a particular monitor is recommended for you.
Advanced Cardiology accepts most major insurance plans, and coverage is verified individually. Coverage for MCT usually depends on medical necessity and your plan’s rules, and some plans require prior authorization, so please confirm with our office or your insurance provider before monitoring begins.
MCT gives your cardiologist a detailed picture of your heart rhythm over time, which can help with decisions such as:
Starting or adjusting heart rhythm medicines (such as beta-blockers or antiarrhythmic drugs)
Referral for procedures such as ablation or pacemaker implantation when findings support it
Diagnosing hidden arrhythmias that may explain fainting or palpitations
Checking how well treatment is working for an existing heart rhythm condition
A sensor or patch is placed on your chest and paired with a small transmitter or built-in cellular connection. Keep the device charged and within range as instructed, and press the symptom button or log symptoms when you feel them. Ask how to shower with your specific device. Most people can continue normal activities. Keep taking your medicines unless your care team gives you specific instructions.
MCT is non-invasive. The most common issue is skin irritation from the electrodes or adhesive. Let our office know if your skin becomes sore.
The monitoring center sends reports to Dr. Khalid during and after monitoring. If a finding needs attention before your follow-up, you may be contacted with instructions. Dr. Khalid will review the final report with you and explain next steps.
The monitoring center follows notification criteria set by your physician, and some findings may lead to a call. However, MCT is not an emergency response system and you should never wait for a call. If you feel symptoms of a possible heart attack or stroke, call 911 yourself.
The length depends on your symptoms and what your cardiologist is looking for. Many people wear MCT for days to several weeks. You will be told when to stop and how to return the equipment.
