After I had my angiogram, I had to have drug challenge tests done to see if I had Brugada Syndrome or Long QT Syndrome. I had never heard of these syndromes before and the Cardiologists had explained each to me. Brugada Syndrome is a genetic disease and can be found by an abnormal electrocardiogram (ECG) and an increased risk of sudden cardiac death. Long QT Syndrome is a disorder of the heart’s electrical activity and it can cause sudden, uncontrollable, dangerous arrhythmias in response to exercise or stress. They say that people who have Long QT syndrome can have arrhythmias for unknown reasons. However, not everyone who has Long QT syndrome has dangerous heart rhythms but if and when they do occur, they can be fatal.
The Brugada syndrome the test was done as a ECG with medication, where they put the probes on your chest that record the electrical impulses that make your heart beat, and these electrical signals can help them detect irregularities in your heart’s rhythm and structure. Your heart rhythm can change and sometimes the ECG may not detect the abnormal heart rhythm so that’s why the doctor gave it with medication thru my IV. That test came up negative.
The Long QT syndrome test was done as a nonexercise medication stress test. An ECG test is performed while you are given medication that stimulates your heart in a similar way to exercise. This drug was also inserted into my IV. The drug has an adrenaline substance that your body releases in response to stress. So in this stress test, the doctors monitor the effects of this adrenaline on the way my heart recharges. They said that this test can unmask in some people what is known as concealed Long QT syndrome which is a normal Q-T interval at rest. Doctors also said that some people who have Long QT syndrome, fainting spells are sometimes triggered by sudden bursts of adrenaline in the body, such as intense exercise or emotional upset. That test came up negative.
They did all the testing that they thought that they could do for me and still had no answers on why I had collapsed that fateful day. The Doctors were stumped! because the tests came up negative, they decided that they wanted to have a genetic test done for Long QT syndrome.(which I had a consultation on May 9th) Meanwhile they had discussed putting something foreign in my body. The foreign something is a device called an Implantable Cardioverter Defibrillator (ICD). An ICD?? I was given a manual, (well I call it a manual) it’s a pretty thick booklet on this device and I couldn’t believe what I read! The definition of an ICD is a small battery-powered electrical impulse generator which is implanted in patients who are at risk of sudden cardiac death due to ventricular fibrillation and ventricular tachycardia. The device is programmed to detect cardiac arrhythmia and correct it by delivering a jolt of electricity. A shock? I was scared when I read that!
After all the discussing with doctors and my family, it was best that I had this implanted due to the nature that they had no answers why I collapsed and it possibly could happen again. And if it did happen again, who knows if I would survive? On January 31 they had implanted the ICD. The first picture is what the device looks like outside the body and the other pictures are the healing process of inside my body.
