Abnormal Heart Rhythms (Arrhythmias)
What is an arrhythmia?
The word arrhythmia comes from the Greek (meaning "without rhythm") and refers to an irregular heartbeat. If you have an arrhythmia your heart may beat too quickly (what's known as tachycardia) or too slowly (a condition known as bradycardia), or your heart may simply beat erratically. All arrhythmias occur as a result of disruption of the electrical signals that tell the heart to beat at regular intervals of 60 to 100 beats per minute.
Symptoms of arrhythmias
While some people experience no symptoms of arrhythmia, others may notice:
- Heart palpitations or fluttering
- Pounding in the chest
- Shortness of breath
Types of arrhythmias
While some types of arrhythmias are harmless, others such as ventricular fibrillation and atrial fibrillation can significantly affect the heart's ability to pump blood, which then affects blood flow to vital organs.
Causes of arrhythmias
Arrhythmia may be caused by behavioral and lifestyle factors such as stress, drinking too much caffeine, or smoking, or by medical conditions such as high blood pressure, heart disease, or an electrolyte imbalance in the blood.
People with atrial fibrillation (AFib) have a five times greater risk of stroke—and stroke that is related to AFib is often more disabling and fatal. Our goal is to help reduce your risk of stroke and sudden cardiac death with a range of treatment options that includes medication therapy, radiofrequency ablation, cryoablation and implantable devices with remote monitoring.
For our patients with heart rhythm disorders such as atrial fibrillation and ventricular tachycardia, our experienced team of electrophysiologists, cardiac surgeons and advanced practitioners will work together to develop a treatment plan just for you by applying the most innovative and least invasive techniques and procedures available.
Why choose Lankenau Heart Institute for cardiac arrhythmia care
Conveniently located just outside of Philadelphia, Lankenau heart Institute has a highly specialized cardiac arrhythmia team known worldwide for their experience in the diagnosis and treatment of heart rhythm disorders.
Here are a few more reasons to let us care for your heart:
- Access to breakthrough technologies and treatments. Our clinicians have been involved in research resulting in FDA-approved blood-thinning medications to reduce stroke risk. We also have expertise in implanting newly approved left atrial appendage closure (LAAC) devices (WATCHMAN), which prevent movement of blood clots that can cause stroke in patients with atrial fibrillation.
- Device implant experience – volumes. We are a high-volume center with vast experience implanting pacemakers and ICDs (implantable cardioverter defibrillator), including the leadless Micra Transcatheter Pacing System and the MRI-safe cardiac resynchronization therapy defibrillator (CRT-Ds).
- Remote monitoring – a watchful eye on your heart at all times. Short- and long-term monitoring of your arrhythmia device allows us to diagnose and monitor your condition, and act quickly if needed.
- Expertise in catheter ablation. This minimally-invasive treatment for ventricular tachycardia allows our surgeons to send energy to the exact region of your heart where irregular heartbeats originate and to destroy tissue that may cause irregularity.
- Ability to identify inherited heart rhythm disorders. Our experts have experience diagnosing hereditary arrhythmias such as long QT syndrome and Brugada syndrome. Diagnosis involves a complexity of testing and skilled interpretation of the results to help us understand what’s causing your arrhythmia—and how the genetic trait may affect other family members.
- Specialists in removing pacemakers and leads. Removing pacemakers and defibrillator leads is a complex procedure performed by our skilled specialists with surgical support on hand. Nearly 95 percent of our patients have their leads removed without the need for open-heart surgery.
