This is an image of a square. Inside of the square is a line which looks like a heart rate monitor chart. There are four peaks on this line and they are all of varying sizes.
This is a ECG Filled icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
