Heart Care · Cypress, TX
Heart failure means the heart cannot pump enough blood to meet the body’s needs. An arrhythmia is a heartbeat that is too fast, too slow or irregular, and the two conditions often occur together. At Cypress Cardiovascular Institute, board-certified cardiologists evaluate and manage both with echocardiography, heart rhythm monitoring, medication, cardioversion and pacemaker or defibrillator care for patients in Cypress and northwest Houston.

Understanding the Conditions
Heart failure is a chronic condition in which the heart muscle cannot pump enough blood and oxygen to support the body’s organs. It does not mean the heart has stopped. Heart failure can result from a weakened heart muscle (reduced ejection fraction) or a stiff heart muscle that does not fill properly (preserved ejection fraction). Common causes include coronary artery disease, high blood pressure, valve disease and a previous heart attack.
An arrhythmia is a problem with the rate or rhythm of the heartbeat. Some arrhythmias are harmless; others, such as atrial fibrillation (AFib) or ventricular tachycardia, can raise the risk of stroke, heart failure or sudden cardiac arrest. Heart failure can trigger arrhythmias, and a persistently fast or irregular rhythm can weaken the heart over time.
Symptoms
Heart failure symptoms usually develop gradually as fluid builds up and the body receives less blood flow. Arrhythmia symptoms can start and stop suddenly. Some people with arrhythmias, including atrial fibrillation, have no symptoms at all.
Breathlessness with activity, when lying flat, or waking up at night short of breath is a common heart failure symptom.
Fluid retention in the legs, ankles or abdomen, or gaining several pounds over a few days, can signal worsening heart failure.
Tiring easily or being unable to do usual activities because the body is receiving less blood flow.
A racing, pounding, fluttering or skipped heartbeat is the most common arrhythmia symptom.
Lightheadedness or passing out can happen when the heart beats too fast or too slow to pump enough blood.
A lasting cough, sometimes with white or pink-tinged mucus, can come from fluid backing up into the lungs.
Call 911 if you faint, have chest pain or sudden severe shortness of breath, or if a fast or irregular heartbeat comes with chest pain, confusion or fainting.
Causes & Risk Factors
Heart failure and arrhythmias share many causes. Conditions that damage or strain the heart muscle, or disrupt the heart’s electrical system, raise the risk of both. Treating these underlying causes is a central part of heart failure and arrhythmia care at Cypress Cardiovascular Institute.
Diagnosis
Your cardiologist reviews your symptoms, medications and medical history, examines your heart and lungs, and checks for fluid buildup. Tests confirm the diagnosis, measure how well the heart pumps and record your heart rhythm during daily life.
Ultrasound imaging that measures ejection fraction, the share of blood the heart pumps with each beat, and checks the heart valves.
A quick, painless recording of the heart’s electrical activity that can identify many arrhythmias and signs of heart strain.
Wearable monitors record your heart rhythm for a day or longer to capture arrhythmias that come and go.
Treadmill or nuclear stress tests check for coronary artery disease, a common cause of both heart failure and arrhythmias.
Advanced heart rhythm testing and analysis helps identify the type of arrhythmia and where it starts.
Blood tests may be ordered to look for heart strain and related conditions, and pacemaker and defibrillator checks confirm an implanted device is working properly.

Treatment Options
Heart failure and arrhythmia treatment focuses on relieving symptoms, protecting the heart, preventing stroke and hospital stays, and treating the underlying cause. Many patients need a combination of medication, lifestyle changes and, in some cases, a device or procedure.
| Treatment | How it works | Typically considered when |
|---|---|---|
| Heart failure medications | Medicines can reduce strain on the heart, remove extra fluid (diuretics) and improve symptoms and long-term outcomes. | For most people with heart failure. |
| Rate and rhythm control medications | Medicines slow a fast heart rate or help maintain a normal rhythm. | Atrial fibrillation and other fast arrhythmias. |
| Blood thinners (anticoagulation) | Lower the risk of stroke caused by blood clots forming in the heart. | Atrial fibrillation or flutter with stroke risk factors. |
| Cardioversion | A controlled electrical shock, given under sedation, resets the heart to a normal rhythm. | Persistent atrial fibrillation or atrial flutter. |
| Pacemaker | A small implanted device that keeps the heart from beating too slowly. | Symptomatic slow heart rhythms (bradycardia) or heart block. |
| Implantable cardioverter-defibrillator (ICD) | Monitors the heart rhythm and delivers a shock to stop a dangerous fast rhythm. | High risk of sudden cardiac arrest, including some patients with heart failure. |
| Treating the underlying cause | Opening blocked arteries or treating valve disease, including TAVR and MitraClip, can improve heart function. | Heart failure caused by coronary artery disease or valve disease. |
| Lifestyle changes and cardiac rehabilitation | Limiting salt, tracking daily weight, staying active and taking medications as prescribed. | For everyone with heart failure, as recommended by your cardiologist. |
Treatment decisions are individualized. Some rhythm procedures, such as catheter ablation, are performed by electrophysiology specialists, and your cardiologist will coordinate a referral when needed.
What to Expect
01
Call (281) 955-9158 or request an appointment online. Same-day appointments are often available.
02
Your cardiologist reviews your symptoms, weight changes, medications and history, and examines your heart and lungs.
03
An echocardiogram, EKG or wearable heart monitor may be ordered to measure heart function and record your rhythm.
04
Heart failure and many arrhythmias are long-term conditions, so your plan includes follow-up visits and medication adjustments over time.

Frequently Asked Questions
A cardiologist diagnoses and manages heart failure and most arrhythmias. The board-certified cardiologists at Cypress Cardiovascular Institute provide testing, medication management, cardioversion and pacemaker and defibrillator care, and coordinate with electrophysiology specialists when advanced rhythm procedures are needed.
No. A heart attack happens when blood flow to part of the heart is suddenly blocked. Heart failure is a long-term condition in which the heart does not pump as well as it should. A heart attack can damage the heart muscle and later lead to heart failure.
Many palpitations are harmless and can be triggered by caffeine, stress or dehydration. Palpitations that are frequent or long-lasting, or that occur with chest pain, shortness of breath, dizziness or fainting, should be evaluated by a cardiologist.
Atrial fibrillation (AFib) is a common arrhythmia in which the upper chambers of the heart beat irregularly and often fast. AFib increases the risk of stroke, so treatment often includes a blood thinner along with medication to control the heart rate or rhythm.
Yes. Heart failure usually cannot be cured, but many people stay active with the right medications, lifestyle changes, regular follow-up and, when appropriate, devices or procedures that treat the underlying cause.
Cypress Cardiovascular Institute accepts Medicare, Medicaid and most major insurance plans. Medically necessary heart monitoring, device checks and procedures are usually covered, but copays and prior-authorization rules vary, so we recommend verifying your benefits.
