Most episodes have no symptoms.

Occasionally there may be heart palpitations, fainting, lightheadedness, shortness of breath, or chest pain.

The disease is associated with an increased risk of heart failure, dementia, and stroke.

It is a type of supraventricular tachycardia.

A smartphone is a mobile phone (also known as cell phones or mobiles) with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use.

Smartphones, which are pocket-sized, typically combine the features of a mobile phone, such as the abilities to place and receive voice calls and create and receive text messages, with those of other popular digital mobile devices like personal digital assistants (PDAs), such as an event calendar, media player, video games, GPS navigation, digital camera and digital video camera.

Smartphones can access the Internet and can run a variety of third-party software components ("apps" from places like Google Play Store or Apple App Store).

They typically have a color display with a graphical user interface that covers more than 76% of the front surface.

The display is almost always a touchscreen and sometimes additionally a touch-enabled keyboard like the Priv/Passport BlackBerrys, which enables the user to use a virtual keyboard to type words and numbers and press onscreen icons to activate "app" features.

Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin.

These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's electrophysiologic pattern of depolarizing and repolarizing during each heartbeat.

It is a very commonly performed cardiology test.
